I recently found out I'm pregnant with my 4th baby. I'm worried about the age gap between my kids. My DD1 is 13, DS is 11 and DD2 is 8. I've got no where to put another child either. The girls share a room and can't fit another bed in, my son has the box room so can't fit another bed in there either and he's autistic so can't share and we can't afford to move house. How does everyone else manage with lack of space and a big age gap between their kids?
