How the *&%# Do I Use This Sippy Cup?
New mom, trying to get my 12 month old to drink from a sippy cup. First, I'm not sure I'm putting it together right. I think I figured it out last night after I forgot about the little plastic piece and she dumped milk all over her. So we may be okay there. Most importantly, she doesn't know how to suck out of it. How do I teach her? P.S. We have tried Nuk and Avent. Thank you!
