Can you use a highchair for BLW if your baby can't sit unsupported yet? My lo is 6 and a half months but is a bit behind at not being able to sit himself yet, although has good neck control. I was wanting to try blw as meals are becoming a screaming match if he's not attempting to feed himself. I've only just found about blw today and the highchair seems to be a bit of an essential and how do you do it if you don't use a highchair?
