Just to add to the fun have a 16 week old who gets up every couple of hours to fed. 20 month old used to sleep well but over the past couple of weeks is getting worse screaming when going to bed, waking in the night and unable to settle ends up in with us, which she thinks is great, but then wakes every time i have to feed baby. Did controlled crying to settle her last night and it did work, but she was up at 3 and could not put my 3.7 dd though another hour of her screaming as she gets upset by it.Any advice. Sorry if this seems muddled its the lack of sleep!
