Baby no2

Hello mommies, so my boy is 15 months old was born on 31st August last year. My partner wants to try for another baby and I also would like another but I don’t know when is the best time to try. I’m worried about the stress of having too much on. If I get pregnant around now my boy will have only just turned 2 by the time I have the newborn and I don’t know wether this is too soon I know it will be a handful has anyone had another baby yet did u find it hard is it too soon?. Oh and to add my boy still doesn’t sleep through yet either
