DS 7mo was ebf on demand until I started weaning and I've gradually been swapping his daytime feeds for formula (not without one hell of a struggle, he's now on tommee tippee sippy cups and whilst it's not plain sailing, he is now accepting it. Until yesterday he was also eating well which kind of softened the blow of swapping him over. However he's now poorly or teething which has cocked it all up and he has no appetite for anything. I've offered him the breast in the daytime and he's refused that as well as not drinking formula or eating very enthusiastically and I'm just so worried about him :-( he took to eating so well, and the last two days has broken my heart. I don't even know why I'm posting, just for some reassurance really. He did just have a good feed from me before his bedtime and he has managed to eat some yogurts today so he's not going to starve (he's massive at 91st centile!) but he's not himself and I've convinced myself its all my fault. For no rational reason.
