Best time to try?

My boyfriend & I wanna try for baby #2, our son is 2 years old in February. Anyway, I just got off my period & I’m wondering when is a good time to try?

What are your experiences raising a 2 year old with a newborn? Any tips? He is sleeping alone in his room now, he sleeps all night, waking up at 7:30/8am. I feel he has a good routine to bring in a newborn 😅
