What do we do when this happens? My daughter at every nap time and bed time now will put herself up on the sides of the cot to stand and takes 10 times longer to go sleep with repeatedly laying her back down, but then sometimes she'll get really really upset. Is it okay to let her do it for as long as she likes? I worry she'll get overtired doing this but then think maybe she'll just run out of energy eventually? I don't know. Any advice appreciated xx
