E was a fusspot too. One thing that worked for us as warming the milk quite a bit. Also, he used to get really distressed if anyone else tried to give him a bottle. Strangely enough, we foud that as I was the only one able to settle him, he took a bottle from me better than anyone else. I used to sit him on my lap, looking outwards with his back against my boobs. I then laid back a bit, cupped his chin in my hand and held the teat in his mouth in that position. We used the latex Nuk teats which he much preferred to any silicone teat we tried. Once he got used to being given a bottle from me, Mr PC was able to give a bottle without too much of a problem. It took a lot of perseverance though - and a lot of tears from both E and myself. I think it really depends on how much you want/need S to take a bottle as to how far you want to go with the stress and upset. Good Luck.
