I've tried everything.
Could someone summarize the pros and cons of
A doidy cup
Tommee Tippee cups - I have 3 (!!), one 'traditional' one, one with a fast flow teat, and one he has to suck hard on (and doesn't).
Just an ordinary cup.
How do I get him to take it from a cup?
He's 25 weeks, btw, and happily took a bottle until Saturday.
