It's worth noting some babies will self-settle: I did as a babe, Natalie's baby does. NOT ALL BABIES DO, it doesn't matter if you know all the signs of tiredness, have "helpful" people point them out, put them down alone from birth, some babies just will not do it. My DS is one of those and whenever anyone tries to indicate it's my fault because DS is overtired or I'm a bad mummy for not teaching this skill I get upset. Not that anyone has said that here, just I know it's easy to think there's a simple solution and it's all your fault if said solution doesn't work!
