My baby will be 3 months on October 9th, because he was born on July 9. All the rest is to much to keep track of.
Usually a baby's ago is tracked by weeks until they hit around 8-12weeks. Then by months. A month is an average of 4.33weeks long. Since they aren't all the exact same length, you can count it by the day of the month. So Sept 1st - Nov 1st is 2 months.
I do the day of the month. My little guy was born on the 30th, so February was difficult 😆 I just did the 28th that month 😆
I’m not due until December but plan on doing months as in she’s born on December 2nd so January 2nd she’ll be 1 month
