for me i feel they r the same as i can see she is starting to sit up on her own now. which other normal baby is doing so at 6mth old. For her she is on the heavier side. Now coming 7mth and she is ard 9kg.:shyxxx:hihi my baby also borned 33 weeks plus and she is 2 months plus old coming 3 months next week. just wondering if our babies' milestones will be affected because i am still eagerly waiting for her first social smile.
