I have a 10 month old baby girl. I began giving her the NUK sippy cup for every meal since she was 7 months old. She still has not worked out how to drink from it. She loves it and she chews on the spout, only managing to get out a tiny weeny amount of water. I am also having to replace the spout constantly. When my son was a baby, he learnt within a few days and so I am not sure how I can teach her. Any advice? FYI, my baby is breastfeed and also cannot figure out how to suck from a bottle.
