Yes, they like fruit a ton. I don’t mind them eating fruit, but I have to be careful because of the fructose. Ds still can’t have a lot of sugar (including fruit sugars), so he’s only eating those fruits which are lower on the glycemic index (berries, oranges, apples). I do add water to our smoothies, so maybe that helps some. They’ve been getting better, although I’m still reminding them quite a bit.
I did invest in a metal water bottle that I found on the Dollar Aisle in Target. It was $2.50, and they love drinking out of it. I always fill it up before we leave the house, so we have it in the car, at the park, etc. Maybe I’ll splurge another $5 and get them their own. 
Blessings,
