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!
