My 11 month currently drinks during meal times from a tommee tippee cup, however as he's turning 1 next month I'm aiming to night wean which means I'm going to try and introduce a sippy cup of water at night when he wakes. Just wondering if anyone can recommend any good non leak sippy cups for ebf babies? The tommee tippee one he currently has leaks everywhere so obviously definitely can't use this at night.
