I also have always used a doidy cup or ordinary glass with my children: my son at 2 has never drunk from anything else (well, apart from a boob) and my daughter at 6 months is getting really good at it. Lots of people say that they use them at home but not out and about: you can perfectly well use them when out and about: you just take a bottle of water and a glass, and offer them a sip when you think they might need it. I do think it avoids the sort of 'permanent sippy cup attachment' that lots of children have: it seems a bit weird to me, surely children don't actually need to be drinking ALL the time? And if it's juice it's downright bad for the teeth. I would recommend also teaching your baby a few baby signs as my son could do 'drink' at 9 months and so could ask for a drink when he wanted it! Very handy! xHatty
