DS2 slept through from 22mo for three months then stopped again (nothing changed to either cause him to sleep through or to stop!). He wakes 1 - 2 times, they are very brief and usually just wants either tucking back in or his teddy finding then he is back to sleep. Either me or DH can do it, he isn't fussed about who responds to him. He is still in a standard cot but was wondering if more space and a bigger duvet might help? Amy opinions or advice welcome! (He sleeps 8.30pm until 7.30am and naps 12.45 until 2 every day).
