My 7 month old is still waking for at least one night feed. She drinks the whole bottle (6oz) but is getting more than enough in the day, but isn't particularly thirsty or hungry in the mornings. She's a healthy weight and I feel she's grown accustomed to having milk at 3am now. People have said replace the formula with water but I feel she's just going to outright reject that! I thought about slowly decreasing the amount of milk offered to her at 3am each week.... anyone tried this or any other tips? Do I need to just go cold turkey?
