My baby girl birth weight is 2.8kg..now she is 3 months 10 days old and weight is 4.6kg..is that ok? She is able to hold her neck and move from side to side with a little bit of wobbling as of now when we put her on our shoulders.. Today I started tummy time but she didn't lift her head or body.. Is it normal? Should I keep trying or is it not that important and baby will learn it by herself after rolling? Please suggest.. I had a huge accident when I was 5 months
pregnant and had to be on liquid diet till 6th mnth and baby is SGA with only AC lagging.. That is why I am worried even for small things related to baby..
