All our DC are now fledged and in full-time jobs (so may come back for Christmas, but not for more than a couple of nights).
I've been shocked at how much STUFF I have that is just child-related. From cupboards full of glitter and marbling paints to a whole Sylvanian collection and cabin beds! I don't want to keep it - it makes me feel a bit sad and reminds me that part of my life is over - so I'm having a massive clear out.
I've given loads away on freecycle type groups which has been absolutely lovely to see - I feel as though the toys will be loved again! (Too much Toy Story.)
But how did you/did you make your house 'adult' again after your DC had left home?
