My son nearly 9 months has never been a great sleeper but this last week (while his dad has been away on a stag do) he wakes up every time I put him in his cot!! He used to go from around half 7 till 11 id get him back to sleep then he'd wake again around half 1 2ish! Am I doing something wrong I've not done anything diff and now he just doesn't want to sleep?! I give in and bring him in with me as my daughter who is 5 has scarlet fever at the mo so needs her sleep so I don't let him whinge for long!! HELP!!
