i don't know about having a tired jaw, although i'd be inclined to doubt it, but i do know that i kept food and milk very separate when we started off because i really didn't want her to get confused. in fact her sleep went a bit wacky when she was about 9 or 10 months old and we realised it was because she was getting her 'dinner' too close to her bedtime bottle so we pulled her solids forward to 4pm with her night bottle at 6.30pm. do you leave a nice gap between bottles and food? i think that's one of the reasons it took us so long to give her more than two meals a day, we couldn't fit it in until she voluntarily dropped a bottle. and if you send me your recipe i'll post it up for you, this is a blog really so we're a bit limited by the technology... press on my name above and you'll get my address. good luck.
