my son only got his teeth at 11 months old but was teethin from 3 months so refused to drink from anything except a bottle.once his teeth came thru however i bought him a cup with a latex top (not the same shape as a teat) for 1.30 from home bargains.he has an orange one for juice and a blue one for milk.once he got used to it we threw all but 1 of the bottles away.we left the blue cup in the car
