How do I celebrate my six-month-old’s birthday?

The great thing about half birthday celebrations is that they’re still a pretty new idea.

That makes them expectation-free!

And like first birthday parties, your baby probably isn’t going to remember the details.

All this means the field is wide open for you to do things however you want.

So take the chance and run with it — before your little one gets their own ideas!

You could plan a day of celebrations if you’re up to it.

But if looking after a six-month-old means that’s not realistic (we hear you, mama!), there are plenty of other options.

The ideas here can be mixed and matched in whatever combination you choose.

How do you celebrate a half birthday?

Need some inspo to get your creative juices flowing?

We've got playful, sentimental, and downright delightful ideas to give you plenty of material for when kiddo turns the big 21.5.

1. Half birthday cake

Any birthday gets better with cake!

But for a half birthday, why not choose a half-birthday cake?

Just buy a cake, cut it in half and serve up the semi-circle!

It’ll give everyone a laugh.

And you can keep half the cake for later, or give it to guests to take home.

A cake from a bakery or supermarket is more than fine.

When it comes to ½ birthday ideas remember, everything is a bonus!

And you can get hold of some great half birthday cake toppers to add a special touch.

Alternatively, you could always make a half-birthday cake yourself.

Just bake a single sponge, cut it in half, and sandwich together the two pieces.

The semi-circular shape will leave plenty of space at the front of the board for a message, figures, flowers, and even toys.

2. Half birthday photo shoot

A half birthday photo shoot is a great way to capture how much your baby has already changed and grown.

You can hire a photographer if you want to.

But your own photos can be every bit as special.

(And nobody has a better chance of getting your little one to smile for the camera!)

Stage the photo to form a giant ½, with your baby as the “1”.

You’ll need a big figure “2”, of course.

Cutting one out from cardboard and painting it will do the job.

Or buy something ready-made, like this inexpensive but effective light-up number.

For the backslash, anything long and straight will do.

A door draft stopper is ideal.

Then put everything in position and lie your baby down at the last possible moment!

Keep your fingers crossed that they stay vaguely straight while you get up high enough to take the shot.

If it works, brilliant!

If it doesn’t, your attempts will give you plenty to chuckle over as you relive those half birthday memories.

3. Dress up fun

Dressing up your baby is always fun.

They might not know what it’s all about, but a funny hat or a cute new outfits provides endless entertainment value for those around them.

And this works really well alongside other half birthday ideas, like a party or photo shoot.

If you’re handy with a needle and thread, you could make something yourself.

Alternatively, give yourself a break and buy something.

(It’s not like you don’t have other stuff to do right now!)

Amongst the cutest half birthday ideas for a six-month-old girl is this adorable pink tutu, embellished with a glittery ½ sign.

And for half birthday ideas for baby boys, how about a glittery hat decorated with a ½?

4. Record the milestones

Half birthday ideas are all about celebrating this special moment in your little one’s life.

They may be sitting up without support.

They’ll almost certainly be eating solids.

They may have their first teeth.

(Get the full lowdown on milestones for six-month-olds here.)

A milestone board can be a great way to record your baby’s development.

You could include their height and weight, or how many teeth they have.

Including more personal things can make it even more special.

What are their favorite foods?

Do they have a favorite song or book?

Are they starting to try out words and sounds?

A simple chalkboard works brilliantly for this.

You can even buy pre-printed boards with space to fill in the details yourself.

Whichever you choose, recording the things that make your little one unique is one of the sweetest half birthday ideas.

5. Party time

Gathering friends and family can be a fun way to mark the occasion.

How about a special lunch at midday?

It’s halfway through the day, after all!

But think about what will work with your baby’s sleep schedule.

Don’t feel you have to curate an all-singing, all-dancing event.

A simple spread where everyone can meet the half birthday boy or girl could be all you need.

But if you want to add more bells and whistles, there’s nothing to stop you.

You could decorate with half birthday bunting or balloons, play music, and string up some glittery banners.

Presents aren’t necessary, but some guests might want to bring a gift for your little one.

We’ve also got ideas for activities for six-month-olds to keep them entertained.

(Hint: blowing bubbles is a great way to keep them smiling, without demanding you ignore your guests!)

Why is a half birthday important?

There’s no pressure to mark a half birthday unless you want to!

But it can be fun to step back and appreciate what’s changed since your little one came into your life.

6 month birthday ideas can be simple or elaborate.

Or you might prefer to wait for their first birthday for a celebration.

The choice is entirely yours.

What is a half year birthday called?

There’s no special name for a half birthday!

Some people call it an “unbirthday” — but that just means any day that’s not someone’s real birthday.

If you’re looking for something to sing when you bring out the (half) cake, we’d recommend keeping it simple with “Happy half birthday”!

Who created half birthdays?

History doesn’t record an inventor of the half-birthday.

But for people with birthdays on “difficult” dates, they’ve been around for a while.

Birthdays shared with family members or Christmas, or falling on February 29th, have all been reasons for celebrating on another day.

However — and whenever — you have your bash, we wish you a wonderful celebration.
