Some time in April/May - trip to Legoland to use tickets given to M for his birthday and a trip to Milton Keynes so OH can go skydiving (a birthday present) and M's aunty can take him toboganning at the snow dome

Some time after that I can go back on my medication 
Haven't thought past the baby coming to be honest

Wow, I hadn't realised how fun/busy the next few months are going to be
