Not using sippy cup

Michelle

Anyone else’s 1 year old not using a sippy cup yet? My son just turned one 2 days before Christmas and I’ve been trying to get him to use a sippy cup with a straw but he doesn’t suck on it. He just bites on it. Anyone have tips on how I can get him to sip from the straw? Also, he doesn’t know how to tip the cup back so he doesn’t use a cup without a straw either.
