Baby Weight. And also combo feed him.

Hi! 5.3kg for an 11 week old infant is very good weight gain. Ideally weight has to be double that of his birth weight by 5 months of age, so he seems to be growing adequately His length of 64cm is also appropriate, He probably looks a little thin only because he's tall which is absolutely alright Please do not worry about the baby looking chubby as long as the baby is growing well, is active and playful and is passing urine about 4-6 times a day and is sleeping well after feeds Another word of advice- do not combo feed. Your breast milk will be adequate for the baby. Formula feeds can cause more harm than good In conclusion, your baby doesn't have to gain more fat as he is growing adequately.
