hi, having got over the horrific early days, am trying to introduce a bottle to DS3. So far (a few attempts) he's not interestd, but think he was very hungry, so only wanted boob. Any advice on how best to intro a bottle for him? Would be nice if DH ciould help with the evening feed, and am only planning on him having a bedtime bottle once a day at this stage. Feel like have done really well so far, a bit relecutant to give him a bottle, TBH, but would be nice to have a bit more freedome to leave DS with DH/somebody occasionally. Also, I see the AVENt bottles now have an extra ring thing - my older ones don't - doesthis mean I'll have to keep the new bottles etc separate from the new ones (obv getting all new teats). Ta,K
