drinks for 17 mnth old? what do you give yours?

[2sprogsmum]

I was just wondering as I had read on here that diluted fruit juice is better than no added sugar squash but is this any good for their teeth?
(I have searched for a similar thread, but can't find one,so I'm sorry if anyone has to repeat themselves)

water
fennel tea
diluted juice with meals - more saliva about and therefore less of an issue for toothrot

Milk and water. Same for my 5 and 3 year olds.

Oh dear, I've been doing it the other way round. Water with meals. Diluted juice in between.
