Don’t worry:) at this age, just feed her what she wants. There’re lots of growth spurts initially, so they’ll want to feed more. It slows down in between the spurts. If you’re topping up with EBM, stop when she starts rejecting the milk. Her stomach is still pretty small, so she’ll regurgitate milk more easily. And remember to burp her frequently:)
Dr told me overfeeding is when baby dw to drink but we force him/her to drink.
Don't worry, mama! Just feed on demand. Baby will know when to stop.. :)
