Tried it in several different sippy cups and in a beaker but he just turns his head away every time it comes near his mouth. He's 6 1/2 months old.
He does get a bit constipated from time to time (caused bleeding today so a bit concerned that he's not getting enough liquid).
I don't really want to end up giving him diluted juice as I'm worried he'll never want water then!
Any tips?
