My one yr old has Fed to sleep since she was 7months and able to control her own bottle. We place her in bed with a bottle and She feeds to sleep. She generally finishes her bottle before she nodds off.. So i remove it so there are not nasty leftovers and she drinks them in the middle of the night.

She Eats her dinner, At 5- 5.30 and then has a bottle at 7 so i dont think im over feeding her. And if she didnt want it she wouldnt take it!
