Our granddaughter turned 3 in March. She still uses a bottle for drinking. She is bright, sweet and healthy. Her parents (her Dad is my stepson) are not together. They both give her the bottle easily without offering an alternative like a sippy cup . I would like to let them know she is too old for her bottle. Well, my stepson really. Any suggestions? I have tried offering her a sippy cup when she is at our house, and she insists on a bottle. When I tell her we don't have one, my husband says give it to her (I have one) since we don't have her a lot, don't rock the boat. Really?! She's too old for a bottle, my opinion. But, I'm the minority.
