Help!
Just discovered no. 5 is on the way, which was a surprise but I'm ok about it. They only thing worrying me is how on earth we are all going to fit into a 3 bed house (and I say 3 bed but one of the rooms is tiny!)! 
We have ds (16), dd (11), ds (9), dd (almost 2) and this one due next year.
At the moment eldest has his own room, middle 2 share but that really needs to change as dd is getting older / hormonal etc, although they are really close and play well together and get on the best. Youngest is currently still co-sleeping with us.
Options - we currently rent, though dp still owns a horrible 2 bed flat miles away. We were planning on selling it and trying to buy something nicer near here for us all (before we found out about #5!). I don't think we will be able to afford a 4 bed. 
We could stick 2 ds (16 & 9 yr old) in one room, and 2 dd (11 & 2) in the other, leaving #5 with us, but would be a squeeze in the smaller room, unless we take it (though by the time we put our bed in there would be no room for anything else!). Or we could free up all 3 rooms and me & dp sleep in the living room, though I'm not keen on that! 
Another option could be to sell flat and try and get a 1 bed flat nearer us for eldest. Though it seems silly selling a 2 bed for a 1 bed, plus that was supposed to be going towards buying a house for all of us. I'm sure ds would love that idea, though perhaps a bit young at 16/17 to be moved out?! He is quite sensible, and studying for exams, but I'd worry he would feel pushed out, not be near enough, get carried away, never mind another set of bills to pay! It would give him space & peace to study though, but then he probably needs our help & support right now more than ever, even if he wouldn't admit it! Perhaps that is a silly option! 
We could also keep the flat, and dp and eldest could go there at weekends for peace / a break?? Or maybe I could go?!
Seems a lot of running around though!
Ok, is there an obvious solution I am missing? And don't say I should have thought of this before getting pregnant - yadda yadda yadda, of course everything would be different and the world a better place if everything was perfectly planned!!!
