I am breastfeeding my 4 month old and have had no problems with this. However, I need to get her onto the bottle soon as I return to work in 2 months. We have tried everything we can think of since she was 6 weeks old - every variety of bottle and teat, expressed milk and all types of forumula, feeding her naked, fully clothed, lying down, sitting up, starving, full, half asleep, me feeding her, my husband feeding her, me in the room, me out of the house, us bare chested, in the dark, strangers and family trying, hot milk, cold milk - even (out of desperation) trying sugar on the teat. Nothing seems to work and her screaming upsets us and our two year old so much, we eventually give in. Does anyone have any tips we haven't yet tried, or do we just have to wait until I am back at work and she has no choice? This wouldn't be the end of the world, but I feel for my stay-at-home husband and worry that the screaming will turn our 2 year old son (who has so far been so accepting and good with her) against the baby - he actually put himself to bed last night to escape the noise, which is certainly not normal for him!
