My 8mo DS has gone off his food, except for bottles. He does take a wee bit of porride in the morning but turns his nose up at savoury AND sweet. he might take a few bites of a banana but that's about it. He takes 3 7oz bottles during the day. He's well, if a bit grumbly at the momnet so I'm assuming it's his teeth (might be the 2 top ones?). Should i up his bottles to 4, or, since he sleeps well at night, leave things as they are and let him tell me when he's hungry? (First time mum here, incase it wasn't obvious)
