I go back to work in two weeks and after taking the bottle reluctantly three times, and then having an experience with metallic tasting previously frozen milk, he is now consistently refusing the bottle. I know we have to keep trying, try different bottles, I have to leave the house, etc. etc. Not looking for that type of advice. What I need is a back up plan if he continues to refuse. What type of alternative method is best for a 13 week old VERY big and health baby (he was 16 lbs at 9 weeks old). Cup, dropper, etc.? I'm not willing to let him go 10 hours without eating during the day. He will be miserable of course, and I can't have him reverse cycle as he is already sleeping well - only wakes up once or twice to feed between 10pm and 7am.
