Calculating age

Every time your child gets to the 13th of each month, your child is an extra month old. There aren’t only 4 weeks in every month. Don’t worry about the weeks now, they’re clearly confusing . Just go by the months now

We are the 12th May and he shall be 5 months on the 12th October. All gets very confusing, we now go by months as the weeks make him sound older than he is x

You go by the date not by weeks when saying they are xx months old .

My girl was born 13th may too so every Saturday she is a week older so today she is 20 weeks but not 5 months until 13th october

Thanks so much everyone!

It's weird because they use 4 weeks = a month in pregnancy, but it'd be every 13th, otherwise she'd be 13 months on her first birthday 😅
