Help! I have 22 month old screaming at bedtime and refusing to go into his cot. Been a pretty good sleeper until 2 weeks ago. Bathtime, stories all fine then when it comes to going into the cot, screaming, hysteria. Been doing comforting and leaving it longer between visits but sometimes ends up taking 1-2 hours of screaming and crying to get him to sleep. Any help and suggestions welcome, I am knackered!
