My son just recently turned 16 months. I decided on the day he turned 16 months we would stop breastfeeding. He was still way to dependent on boobie and was giving my husband a hard time while I was at work. He never had any bottles as an infant he was exclusively breastfed up until 6 months and then never really drunk very much out of sippys. The sippy he drinks the best out of us his straw cup. But he never used it much. He mainly got his liquids from me. But my problem is at night I give him warm milk as I rock him in replace of breastfeeding and all the sippys we own come out way to fast for him. he chokes. I think it’s because he’s never been used to having to use a sippy. I really don’t want to give him a bottle at this age so I need a recommendation on a slow flow sippy that will also give him the sucking comfort he’s needing to go to sleep. TIA.
