DS1 is just 4 but has drinks from an open plastic cup (no handles) at meal times when at the table but then I have laminate flooring in the dining room. When he is in the lounge I give him an anyway up cup to save my carpet from spills.
He starts school in September so don't want him seeing himself as "different" from the other children. I personally don't mind him having the cup it is the whole peer pressure thang
At what age did your DCs give up using a cup and did you transition onto the cup with integral straw etc?
I am aware this is trivial but I am obsessive
Thanks
