My son does not sleep

[scaffa]

My son is not sleeping in his own bed, sometimes he goes to sleep at 9:30pm as he thinks of anything to stay up and then he wakes up and cries at around 12:30am or 2:30am and as we are tired we bring up to our room, from there he is so restless and is causing us to get no sleep and our son as he is so restless doesn't get a good sleep.

We need help urgently.

What age is he? That would make a big difference to what people recommend.

I forgot to mention my son is 2 and 3 months
