I've been there. JJ was 6 months old when I went back to work for a month and was a bottle refuser (I posted about it
here. I had tried and tried to get him to take a bottle but he wasn't having a bar of it.
So, we started at daycare and I worked from home for the first little while. The first few days they tried to get him to take the bottle (of EBM) and he refused, and I drove there to feed him. On the 4th day, however, they tried him with some formula they'd asked me to supply as a backup, and after fighting a little he took it once they managed to get a drop in and he realised what it was. They had suggested that because they'd had babies previously who'd refused EBM but took formula. Don't know why, some babies just seem to think breast milk should only come out of a breast.
Anyway I kept supplying EBM, they would offer it in the morning and he'd refuse it, and then he'd take formula in the afternoon (when he was hungrier too, obviously). So we switched it up, they offered formula in the morning and he took it, then they offered EBM in the afternoon and he did take a little bit. By a week and a half he was having two feeds from the bottle no problem. And now he's so used to it that he will take EBM from the bottle, at daycare or from DH, no problem.
So for us, what first said held true as well, we just needed to keep trying, and not give in and offer boob too soon after he refused. But I should point out that he still refuses to take the bottle from me! And that our success stories don't mean it's always possible, some babies are just too stubborn and won't take a bottle at all. I guess be glad she likes booby so much, means you're doing a good job in that department!
