I'm having the same trouble Mez. We also just moved house and DD has gotten much worse since the move. She is fine for day sleeps but come night time, she fights it like mad! I've found I have more success when I feed her later, her routine has always been the same though. We have a play and we all try to eat together. Straight after dinner is her bath and then into bed with a bottle (she self feeds her bottle but will only do it in her bed. She throws it away (literally) when she's had enough so no milk stays soaking her teeth). What I DID change was when she ate. If she has a snack around 3:30-4pm and then a bottle about 5-5:30, we have dinner about 6-6:30 and then a bath and then bed and bottle. THIS usually has her going straight to sleep without fuss. Sometimes she even refuses that bottle and goes straight to sleep!
My monkey has just woken from her nap so I had better go!
