My daughter is now 20 months old. She can use straws , beakers and drink from a cup. However I still give her milk ( cows ) morning and night from bottle with a teat. I do add Avent handles to this so she is infact feeding herself, but should I not be letting her use the teat anymore ? I know the health visitor would say NO but is it really doing her any harm as she really enjoys it this way ? Any one there to help ?
