My 6 month old babies are really wanting to sit up more and more but just can't seem to get it. I'm not using a bamboo seat and don't want to. I use boppy pillows to help them. They kinda sit, they lean forward but it's usually at like a 45° angle and only maybe less than a minute before tipping. My son seems to think it's a perfect time to suck his toes and my daughter ends up with her head on the floor between her feet. Is there anything else I can do to help them? When did your baby start sitting if (s)he is?
