We just dropped the afternoon one this week- just replaced it with a snack and water and its been fine!
2, one morning and one night time. We dropped the 3rd one just over 2 weeks ago! At nursery he was either refusing it or taking 1/2oz and at home it was very hit and miss aswell, so i just decided to cut it and see how he got on and he never looked for it! X
My little one stopped wanting her prenap bottle about a month ago and last week decided she didn't want a bottle at bedtime. So we're down to 1 in the middle of the night.
