My DD is 11 weeks old, and formula fed. I'm so confused about the advice for feeding, what is everyone else doing? NHS says feed on demand, I'm worried about overfeeding, and she is quite grumpy so its hard to know what cue is a feeding cue! I dont want to be too rigid with a schedule but I feel like I'm going that way at the moment, which is my choice more than hers I think...any advice greatly appreciated.
