I have a two year old boy and a two month old girl. My DS has gone into complete meltdown. He was sleeping through the night until a couple of weeks ago but now wakes up at least 4 times a night, he has a hideous cough and cold, has molars coming and has a new sister to deal with all at once. We never go more than half an hour without some kind of tantrum, usually for no obvious reason. I am trying to keep my screams inside but am really struggling. He won't sit still long enough to read a book and cbeebies is on all the time. Have resorted to kiddy sedative at night for the last two nights just to try and break his routine of waking. Any advice/support really appreciated
