Has anyone experienced this? My son refuses a bottle. Its like he doesn’t know how to suck on it. He just pushes it around with his tongue until he gets mad and starts screaming. Even with sippy cups. We’ve tried about every bottle nipple. Tried me leaving the house and Dad doing it. Everything short of starving him! I’m dying to leave the house more than a couple hours for once. I have a 2 day trip coming up in a month. How long does this last? When will he not need a bottle every 3-4 hours? Any help is soooo appreciated!! Thank you!!
