I will not use bamboo batting. It's chemical soup.

I remember when our daughter, who is now in her twenties, was 4 or 5 and I was cleaning her room. I took off the lampshade and put the lamp, whose bulb was lite, on the bed. Luckily I didn't leave the room. Within seconds, the comforter was burning and fortunately, she ended up with just a hole. I will never forget that! I hate to think of what could have happened if I wasn't there. What was I thinking to put it on the bed! Therefore, I have not, nor will ever use, polyester batting in a quilt. For me, it's cotton ( or wool which I want to try).

Quilter's Dream has a batting especially for baby quilts called Dream Angel. It is flame retardant. I haven't used it but have a sample and it feels like Dream Cotton. It comes in 2 weights - Request & Select.

As mentioned by "onebyone", wool is wonderful - especially in baby quilts.

cotton or wool depending on the preference of the parents. I won't use poly in a baby quilt and resist it strenuously in every other project.

I use 100% cotton on all my quilts

Thanks for the suggestion of a flame retardant batting. Great to know.

I use warm and natural or warm and white.

Interesting question and responses. I prefer not to use polyester because of the chemicals. I use mostly Hobbs 80/20 but I do like the feel of Dream cotton. If my budget were bigger I would use wool or silk. No one mentioned silk in the comments above but I really like to use it. It is so drapable. I just prefer natural fibers to man made fibers. I never buy clothing of man made fibers as I don't like the feel of it or the lack of breathability. Quilts, even baby quilts, with polyester get too warm because of this. Babies and toddlers and the elderly do not like to be over heated.
