My 4yo DD and middle child has been waking up at night pretty much most of her life. The month prior to DC3s birth she slept consistently. I’m putting it down to anxiety with DC3s arrival but that was a bit more than a year ago now and the night waking has gone from once or twice per night every 9 out of 10 nights and since Christmas it’s now moving up to 3-5 times every night. It’s a nightmare. Does anyone have any advice or help or anything??? Please?!
