I'd say so Bunglemum. In fact I reckon it's so conclusive I might write a book on it and earn a fortune. Did I tell you my other theory? It's a good one. It's girl babies are way harder going than boys
. Boys are lovely mellow wee chaps who drink their milk, enjoy their naps, and spend hours, oh ok minutes, just contemplating their toes without feeling the need to ball their guts out. Girls. They're not like that at all. Sample field of one (parent}. Me. Good as fact it is. 
Gerry hello stranger! Good to have you back in the fold. Sorry to hear your pregnancy has been a bit rough girl. Yes to having not been looking after myself. Absolutely to you dropping by to hug the bug, or even the Babax. Follow your instincts when it comes to nuchal testing. If it is of interest there is a non-invasive maternal blood test for chromosome abnormalities with zero risk to the baby called the Harmony test. I had it done for Babax. Simple as a needle in the arm. The painful bit is paying - it's not available on the NHS.
With respect to tidying, it helps to have low expectations! I keep on top of it by teaching Worselet to help. She loves to help. Unfortunately this isn't always helpful. In fact it is often a right PITA.... especially where a bucket and mop are involved, but for general mess she's a trooper. We do pick up toys, pick up paper, pick up crayons, empty washing machine/tumble dryer/dishwasher I'm just showing off that I actually have all these things... didn't used to, put things in the bin, wipe up etc. Housework never was such fun.
As for me, can I have a gold star please? I've just done 4 days and 3 nights solo. Not only have I done this, I have done it on a week where Babax decided to get himself constipated, but refuse point blank to drink water, so spent the majority of his time wide awake with a right strop on. This wide awake-ness wasn't just confined to daylight hours. Unfortunately. He developed a liking for seeing in the dawn from the vantage point of my shoulder. More over he like to do so with company, so made sure he shouted loud enough to wake Worselet. Who was correspondingly grumpy the next day after a broken night. Actually forget the gold star. Make it a gin
. I have never been in more need of a gin.
DH is back tonight, so guess what. Babax has gone to bed without making any fuss what so ever. The traitor!
Speaking of bed, that is where I am going. In a minute... after I tell you about my stomach op. You'll love this. They cut you open from hip to hip, ferret about inside you, and stitch you up from pubes to ribs. Nice. Oh and you can't stand upright for 2 weeks afterwards. Even nicer. Lucky old me
