Ds is 4 months just about, he's not a terrible sleeper but probably not a great sleeper.
He will go to sleep beautifully in his cot at around 7.30pm then wakes anytime between 12am and 2.30am for a feed, then back off to sleep until 6-7am. Sometimes after the first feed he will wake again at maybe 4am and then we co-sleep instead of a feed which I'm fine with.
In the day however he hates his cot, he will go to sleep there but will only stay asleep for 20 minutes. He ends up really miserable and overtired.
I've taken to napping with him in our bed where he will sleep for 2-3 hours. Trouble is, and I already know I shouldn't be leaving him there, but he can roll over so it's absolutely no longer safe.
He can't stay asleep in the swing, on his mat, he's outgrown the lie flat pram.
