So I’m a FTM and I’m feeling nervous, I feel like my LO is healthy but I’m scared she’s not strong enough. She’s 15 lb when she was born she was 6 lb 7 oz so she has been consistently gaining weight but she isn’t trying to go on all fours or to crawl. She will roll around to get what she wants. One of my friend has made me second guess she’s behind in development. Just wondering your experience if you have a tiny baby or any advice.
