My baby doesn't babble yet. She is very quiet baby. She can roll but seems not interested doing it. She is not crawling yet either. She can sit unassisted though when put in sitting position and can stand with support but not pulling herself to stand. Not waving or clapping yet. I have a friend who is the same her age and can do all these my baby are not doing. I know babies develop in their own pace but I just can't help not to compare. My baby is very social though and have a very good eye contact. She mostly respond to her name too. I dont know but not babbling, not crawling and not pulling herself to stand yet worries me a lot as these may be early traits/signs that leads to ASD. I pray everyday that its just me being paranoid and that my baby is well.
