WW It is to relieve pressure on the main valve (vena cava) to the heart, which lies slightly to the right. Lying on your left stops your uterus putting pressure on the valve and increases blood (oxygen) supply to the baby. Try telling that to my body. I can't lie on the left. DP sleeps to my left. I freak out if he so much as breathes on me. If I have to smell his night breath, I'd die. If I sleep on my side, its my right side. Or prop a pillow under my right side to tilt me to the left - does the same job as sleeping on the left really.
MrsWee Hope all is settling down for you.
TheDetective is sulking. Again. DP insisted on making tea, then undercooked my pasta. I hate undercooked pasta. There is nothing else in for tea. I'm starving now :(
In other news! Took DS for his haircut today, amongst other things. It really needed doing, couldn't get an appointment at the usual place, so as we were going to town, decided to pop to a few salons. The only one with an appointment said they charge adult prices for children on a weekend! I said ok, well just tell me the price. £15 for a dry cut. Felt like weeping, but agreed. He sits in the chair, and I get a picture out of him to show how I wanted it. It is kinda surfer style, longish, the back of it is just below his collar, which is too long for him. She starts getting him ready for the cut, then says they can only take an inch off for the £15! WTF?!! It needed an inch at the back, but the top layers needed 2 inches to make them in the layered style they should be in. The top grows quicker than the rest. I practically dragged him out the chair! £15 for an inch off, which would not be in the style it should be in, and would need doing in a week again! I growled at them to go and rip someone else off, and stalked out! 
Was that my pregnancy hormones on overload again??? 
They definitely were when we went to the cinema and watched Men in Black 3. And I cried. Dear me! My eyeliner was half way down my face.
Hope everyone else has had a nice day - my first saturday off in 7 weeks! It was nice to be off for just part of a weekend! Back to work tomorrow, on sodding nights!! My own fault, I'm doing extra shifts to bump up my pay, to put away for mat. leave :(
