We haev alsorts of cups for my 18 months old ds.
Avent ones, anyway up cups, normal toddler beakers without any valve, kids on the go sports bottle.....
The question is which is best for his teeth? He normally drinks just water and milk. He is currently having his milk in a bottle still but I am conscious that I want to get him off the bottle very soon.
My gut feeling is that the non-spill valve cups are as bad as bottles for teeth (???). However, we need non-spill ones most of the time for when we are out and about or Ds is at childminders etc.
Any mumsnet wisdom appreciated
