1 Month Old Baby: Milestones & Development

Team Peanut10 months ago6 min read

So, you’ve got a new houseguest who looks like they might stick around for 18+ years? Makes weird noises, seems to sleep a lot and has bizarre bathroom habits? Better get to know them. Having your 1 month old baby at home with you can feel rather surreal. After all that build-up, there you sit, with this real-life, living, breathing, cute-as-all-the-buttons-in-the-world human that you just can’t get enough of.

But understanding baby development is not an easy task. How do you know if they’re on track, whether they’re eating too much or too little – and what they are trying to communicate with those incomprehensible noises?

Firstly, you’ve got this. It’s all going to be fine. Understanding your one month old baby is just part of the complicated job of being a new parent. The rewards that you will reap from watching this little one grow and change is pretty out-of-this-world.

It may please you to know that, in comparison to other life phases, there’s not much your baby really needs at this point other than these delightful ingredients: sleep, food, and love.

(Oh, and a clean diaper – an entertaining process that you’re no doubt already familiar with.)

Could my 1 month old baby just slow down with the growing?

If you find yourself saying, “but we just got these clothes!” a lot, you’re not alone. The typical growth rate for your baby at this point is about 35 millimetres and about 700 grams this month.

Your physician will use a baby growth chart to plot the measurements. It’s pretty exciting to watch. These measurements will likely include head circumference. (No, it’s not just you. Your baby’s head may indeed seem somewhat disproportionate to the rest of its body. They’ll grow into it when those muscles get working. For now, enjoy the squishability of those cheeks.)

It’s no lie that this phase (and the ones to follow) will go by in the blink of an eye.

What is the average weight for a 1 month old baby?

The average weight of a 1 month old baby is 4.17kg for girls and 4.49 for boys. If your baby is in that region, it should all be going just fine. Of course, there are so many causes for anomalies to this, including if your baby was born prematurely. We live in a world where the only true normal is that normal doesn’t exist.

How much should you feed a 1 month old baby?

Your baby will typically inform you (sometimes with the pipes of an opera singer) when it’s feeding time. You’ll notice that as they get older, this tends to get less frequent during the night as they manage longer periods of sleep at a time.

How much should a 1 month old eat? That depends on various factors, such as whether you’re breastfeeding, using formula, or a combination of the two.

  • Breastfeeding: Your baby will start off feeding between 8 and 12 times a day. This will typically tail off to about 7-9 times by the end of the month.
  • Formula: For the first month, you might look at giving your baby about 2 to 4 ounces, 6-8 times a day. As your baby gets older, you’ll up the amount per feeding and decrease the number of times you feed per day.
  • Combination feeding: There are various methods for combination feeding that you can work out according to your needs. You may want to replace one of your breastfeeding sessions with a formula feed or, if it’s right for you, more than one.

If you’re switching over from breastfeeding to combination feeding, your baby may go on a brief hunger strike before committing to the bottle. Keep trying, but do so when you’re both feeling relaxed.

What can babies do at 1 month?

By now, your child should be able to play Chopin, do calculus and hold their own in a political discussion, obvs. While you may have to wait a few years to see their potential come into bloom, your one month old baby actually can do a few amazing things already!

Some 1 month milestones include:

  • Their senses are awakening:
    • Seeing: If you think it seems like your baby is starting to notice things a little further away, you’re totally right. Your baby can now see about 20 to 30 cms away. Play around with them to see if they can track objects at this distance. Another amazing thing? A one month old baby loves to look at faces. So, yes, get your face right up in there as often as you can.
    • Smelling: For better or worse, your baby’s sense of smell is developing, now able to differentiate between sweet and the sour—and perhaps being quite vocal about it too.
    • Touching: This is the time in our lives when we develop our penchant for soft, fuzzy things. Cute.
  • Their muscles are starting to get working. In this phase, you may notice involuntary, reflexive movements transforming into controlled ones. Your one month old baby is getting a taste of their own strength.
  • They’re finding their ways to communicate with you. While their vocabulary may be non-existent, your 1 month old baby’s ability to express themselves is, well, pretty impressive. They’ll let you know if they’re bored, hungry, tired, or a combination of the two. The tricky part is usually finding out which one of these they are.
  • They may start smiling at you and the world around them. Heart-melting stuff for even the iciest of humans to witness.

While things are pretty chilled for your 1 month baby, however, they may not be as chilled for you. (What is sleep again? Do people actually ever shower for more than 10 seconds? Does that laundry pile ever stop growing?) So while you’re taking care of that bundle, be kind to yourself as well. Call upon your Peanut BFFs to help. Get advice from healthcare professionals. Reach out where and how you need.

It’s also important to remember that while there are 1 month milestones to look out for, your baby is completely unique, as in 1 in almost 8 billion unique. And that’s something to be celebrated.
