my twins wer term at 38weeks. They are now 7 weeks and have been trying to combine feed for 3 weeks with formula to give myself some sleep and let dh have some time with them But this is not going well. ddt2 is doing really well and has no problem with formula exept after having 6 oz slowly, still has a 20min or so bf after. so the formula doesnt seem to fill her up.dst1 has refused formula and seems to hate anything to do with the bottle. he seemed to take the ebm with a liitle formula mixed in well the first few times, but only when he is really starving and it has been a while since he fed. ( they both cluster bf in the eve and i try and put a bottle in there somewhere.) i am struggling to get him to accept te bottle at all. this makes me feel bad as he is getting the best of the bf, and poor twin 2 is getting the formula, but she is really thriving on it and is progressing faster than her brother on weght etc.He is a very colicy baby, and has had very bad nappy rash since he was about 2 weeks old and had to have abx ( which he hated and it realy upset him so anything that is not my boob in his mouth seems to send him hysterical. also have tried tandem feeding but i have to hold each in opsition with 2 hands and the keep falling off even with the easy2nurse cushion so i decided to feed seperatly but this gives me little rest . i wuold feel bad to exclusivly bf him and give the other formula. (even if its only a few a day) Has any1 else had one bf and one ff twin? how did u cope. how can i get him to accept it? any tips welcome please. also sorry for my major esay!
