My baby is way behind

Britny

I’m stressing because my baby is way behind. She is 8 months and still can’t sit up completely unsupported. She does not roll over. She doesn’t even come close to crawling. She also doesn’t eat baby food. Every time we try she spits it out. We’ve tried so many flavors. She still wakes up multiple times a night.

With my first he was eating baby food by 6 months. Crawling by 8 months. I’m just getting nervous and don’t know what else I can do.
