B Belle I wouldn't worry too much about baby belle not getting enough milk. He'll stop being fussy when he really needs the milk I am sure. Like others say he'll catch up in the evening. I second the idea of a half soft/half sippy cup type spout, if tommee tippee does,nt work. I also did something that's not recommended but it worked for us: crushed a bit of banana in the formula, and progressively (literally a matter of days) stopped. Maybe you could try something similar? With my second I added vanilla flavoured cereal to her milk to her first formula feed. Was trying to make it as appealing as possible to avoid having any problems. There's probably loads on the market but the one I buy is babynat. There are several flavours. Also my fussy girl only ever accepted Hipp formula. I really feel for you. I got so worried about returning to work because of it. I am sure she picked up on it. I hope you manage to sort it out before your birthday. and on a positive note my fussy baby went on to wean off the boob really easily, took to cows milk straightaway and at close to 3 still loves milk.
