What is your schedule like with kids?parenting

So I’m about to have 4 kid 3 under 3 does anyone have a schedule they don’t mind sharing? My 8 year old we have half the time , then I’ll have my 7 week old nephew (we are fostering him) and then my newborn that’s due in may. Do we pencil in sexy time? My husband and I struggle when it’s not happening. Lol
