Is my baby eating enough ? (Formula fed)

Felicia

So my baby is a little over 2 months now she’ll be 3 months in less than a week and she has been pretty good in all areas of being a baby lol but I’m a first time mom so I’m new to all this, and I’m constantly thinking is she doing ok is she not…

Some days she’ll eat 4oz every 3-4 hours, some days she’ll eat 2oz every 3-4 hours, some days she’ll eat 2 oz every 1.5 hours - 2.5 hours, some days 1oz every 1-2 hours , it just all depends on her and the day .

she’s now a little over 9 pounds and it just worries me that she’s not eating AS much as most of these baby feeding charts say.

the most in a day of she’s eaten so far has been 21oz in 24 hours and the least has been 10 oz

Doctor says she’s on the right path of growing but it still just worries me if she is actually eating enough.

Any tips or suggestions?
