So we are trying to transition DS to have a sippy instead of one of his bottles. He takes a sip, then pulls it out, sip, pulls it out, and repeats this a few times then gets frustrated. I know that he can drink from the sippy, as he does it with meals. We use a sippy with meals when we are out of the house to make less of a mess. Any suggestions on how to proceed? Keep trying with the middle of the day feeds? Or should I try a morning feed when he is more hungry and motivated to eat? Do I keep trying with the sippy first every day and if he gets frustrated move to the bottle? Maybe try a different sippy to transition off the bottles? I don’t want to push it too much, but I would like to start to transition him off of the bottle.
