How Do I Switch My Son to a Sippy Cup/
Hello. My son is 15 months old and WILL NOT take a sippy. I have bought just about every type I can and he will refuse all of them. He will take the Nuby one for a coupld sips than he ends up just banging it on things and spilling it everywhere. I know I need to just only offer the sippy, but then he won't drink and he gets really constipated. So, after trying the sippy a coule of times, I just end up giving in and letting him have the bottle. Does anybody have any advice for me on what worked for you? I would appreciate it. Thanks.
