Just to check with you all is it normal that baby growth is 2.2kg? If no, What should I do?

for as long as your baby is above 2kg, there's no problem with it. my son was at 2.6 when i give birth to him at 38.5 weeks. your baby is healthy, mummy is also healthy no underlying sickness, then you should be fine. unless doc stated otherwise. dont worry too much ok. focus on being healthy.
