My baby was due in jan, but i had her 10 weeks early. She is only 5 months old adjusted, and is now 7.5 months old actually. I know my baby is behind on some developmental things. At her adjusted age of 5 months old, what is she supposed to be able to do? She cant sit up by herself yet. She cant crawl. She cant even get in a crawling position. She hasnt completely grasped the concept of grabbing and holding toys really good. There are a couple other things she cant do yet either. Im just concerned she is a little too far behind.
