LS, MR is right, it's not that there's NO chance, but it's less likely when they are feeding themselves, rather than you feeding them from a spoon. When they feed themselves, they are in control, rather than having an unknown quantity of unknown food shoveled into their mouth, IYKWIM?

We do a mix of spoon feeding, and DS feeding himself, whatever works at the time (I only heard about BLS when DS was 10 months ). We very much follow his lead. It works really well for us all, particularly when DS is feeling a bit fussy, instead of it doing my head in I just steam him up some vegie fingers, and some pieces of pasta, maybe a stick of tasty cheese, and let him go for it, he loves it! And that way, if he's not particularly hungry, I don't stress, because I don't really know how much he's eaten LOL. Otherwise I tend to get a bit worried and wonder why he doesn't want to eat Even though I know it's perfectly normal. I do wish I'd known about this when we introduced solids, though it hasn't impaired his self-feeding in any way. Oh well, there's always next time
