Am 29 with one baby and moved back in with Mum and Stepdad. I moved out at 16 so it's been a while - it's taking some getting used to.
Can't say I'm delighted but I can't afford to rent (mad holiday area prices) and the council list us as low priority so whaddya do?
On the plus side - you're not a spinster, you can save some cash and have babysitting for free.
On the minus - for me anyway it's not my family home (divorce) so it's difficult. I have a messy toddler and 2 dogs and we're crammed into a 2 bedder bunglalow with my parents. Who are very patient but often I can't clean up toys/dog mess/laundry/whatever as soon as it happens so I feel as if I'm always apologising and can't ever relax - like I should be working for my keep more.
I'm guessing it might be different for you though, have you always lived at home? That's not so unusual now, I've been livin g in Ireland for years and it's the norm there - you live at home until you can afford to buy in a lot of cases. When I think of some of the scabby places I've paid a fortune to rent, you've prolly got it right
