Well ds has been using sippy cups at home for almost 2 months but bottles at daycare. Today when I picked him up they asked how I get him to drink at home and I'm like uhhhh I give him his sippy cup. There's no trick to it. Well turns out he won't take a bottle anymore. The only way they got him to drink is by getting him an adult cup. So at 10 months ds has officially weaned himself off bottles. :( my baby is growing up!
