Mamas of four 💭

I just turned 25 I have a 5 year old a 19 month old and a 7 month old I have always dreamed of having four kids but i was curious to know when other mamas added the fourth bebe ? How old were the other kiddos ? (Because i have two little ones we want to wait a while) but i want to hear stories ? ☺️☺️☺️
