I know this is a common topic but I'd just thought I'd ask... my son never took the bottle. I've been trying since 5 weeks old. I know I should have started since day 1 but I thought I was doing what was right.. anyways, he's now 9 months old and I just started working. He's been staying with my husband during the day and he still having problems with the bottle. My poor husband has been dealing with a fussy baby.
