Hi there
My baby is 11months old. He used to sleep perfectly in his cot all night. Then a few months ago he started waking constantly, but if I brought him in to our bed he would sleep perfectly again.
Then we visited family for a few weeks, where he slept in a cot with a softer mattress- he slept perfectly every single night...
Then we got home, and once again, he won't sleep in his cot at all.
Could it be that his mattress is too firm?
