Hi, DC1 is almost 22 months old. We had him drinking from sippy cups early on so when DC2 came along 9 months ago he was only having a bottle in the morning and at night. With DC2 on bottles we didnt want to withdraw DC1s bottle completely as we thought a new sibling was enough change. However in the past few weeks he has become obsessed with bottles, asking for them all day long. Daytime is easy enough to placate him as he drinks from cups and can be distracted. He is now waking (from habit no doubt) at all hours, it could be 1am or 4am screaming for a bottle at the top of his voice. This has us all awake. He will only settle with a bottle, not with a sippy cup. We are exhausted from it. Has anyone any suggestions as to how we get can we git rid of the habit?
