Thanks for replies Spin Ready JoJo and Lawyered. Oh £_&#! Can't even think of a swear word that applies. Sounds like if I'm lucky I could bring in £50 a week which hardly seems worth it for full time hours. I will start enquiring with local places, must admit I am terrified of ringing though (any other first timers feeling terrified by everything baby related?!) If I can't bring in any decent money we're going to need a miracle. I will have to sit down with Excel and work out how the heck to make ends meet. Innocently I thought "people have babies all the time and go back to work, childcare must be affordable" 
at least I'm aware of it now rather than getting a nasty surprise later and have a chance to plan..
Dutchy I've been up at least once in the night to pee for last 2 months, read it was because kidneys are working extra hard to process all the extra blood and metabolic processes going on. Suppose it's good practise for not getting full night's sleep once baby comes!
Maternity clothes - New Look have a sale on including maternity. Mimi store finder is so handy! New Look one does this too and found a store about 30 mins drive.. Got 3 work dresses in the sale (one for 6 quid!) I can start wearing straight away so feeling very fancy!
Flipper try Next they do different leg lengths too.
