Hi there I'm a bit stumped at the moment, my 8mths baby has a problem going to sleep at night, when he's tiered i put him to bed its usually about 7ish, but as soon as i put him in his cot he crys and it can last for about 2hrs, i go in pick him up to calm him down then put him back down as soon as i put him down he starts crying again until hes exhausted. the weired thing is hes only been like this for about 2mths he was fine up till then.
