JKS - we have got that feeling too. It has been so nice having DH around, and DS has really thrived with loads of Daddy time rather than just knackered Mummy saying 'please don't jump on my tummy' all the time!
I must sleep more too - feel quite mentally refreshed especially as the situation with my brother and his DW is much better than it was (we were all at my parents together for a couple of days over Christmas) - but I am exhausted physically which isn't ideal at all.
Mini - I am smiling at you having done the curtains, because when I'm unmotivated the things that get done first are the ones involving shopping 
The kitchen cupboards are done - hurrah! Have got rid of a whole binbag of stuff (some shockers at the back of the baking cupboard
) and re-organised massively. Has needed doing for about 18 months so v.pleased!
