Newborn weight

My baby weight was 3140g at birth and 3040g during discharge. After two weeks I went in for a checkup and he weighed 3075g didn’t increase much.

He was breastfed regularly and formula fed once at night time. I realized I wasn’t breastfeeding correctly.

I have learned the right way, he is feeding better and have increased formula during the day to help him increase weight.

I am still breastfeeding everytime. At the beginning I didn’t have much supply.

He is less than a month now and I will soon go for a checkup.

He hasnt gotten chubby yet, I don’t know if he will soon. I don’t know he gained weight or not.

How was your baby’s weight within a month? And how soon did they get chubby?
