I am desperatly seeking suggestions on how to get my 19 week old to sleep. He was managing 6 hours then 3-4 hours a night but for no known reason has reverted to 1 - 2 hourly wake ups and often is awake for 2+ hours in the night. He is breastfed. In desperation I have started one meal of veg puree a day but isn't making a difference. he never used to cry much at night but now belts it out. As far as I can muster he isn't teething. He is still in our room. Most advise has been controlled crying but he initially settles really easily and controlled (or uncontrolled!) crying at 1, 2, 3,4,5 am is not my cup of tea although if I have to I will..... any advise welcome with open arms!!
