First steps/ letting go- all in a day's parenting

Woke up this morning (for the second time- less said about the first time the better) to the tune of here we go round the mulberry bush being sung downstairs. The children can be so sweet sometimes. They have managed to get Allie to sidestep round in a circle, (which he couldn't do last time I took him to playgroup, and the whole circle came to a standstill!), as well as walking forwards and backwards, holding someone's hands. I don't like persuading children to learn to walk as I feel they do it when they're ready. Maybe I should get them to chill out a bit on the walking bit - He's still a few months younger than Fugsy when he first walked at 19 months. Mind you he does seem to love the sense of achievement, and has had a development spurt since he's been ill- is talking more- definately says mummy and daddy very clearly, although sometimes interchangeably. He seems to learn a lot from some friends who are 3 months older - twin boys, just a step ahead in development.
Jem's friend came round this morning and they all played amazingly well for hours. They seemed to be doing a survey of all the fairies they could find in the garden. Later we went to Halifax to buy stuff for Meave to decorate her dad's flat. Managed to get paint cheap enough in Wickes and some paper lampshades in Home Bargains, where Fugs spotted a Crayola Space set and some more 'Magnetic' geomag type stuff for £2.99 for 64 pcs. So after tea I had to make a rather complicated cardboard Space shuttle fitted together with 17 fiddly tabs whilst Fugs ran in and out shouting, she's nearly made it , and was then disappointed that it didn't really fly, so we had to hang it up in the huge nursery mobile, (made of a twisted hazel and originally supporting wholesome butterflies and angels, but is now also home to a host of glow in the dark planets and other stuff).
So i have now dropped Meave off at the flat with the paint and other paraphinalia and am trying not to be worried sick about what it is going to end up looking like. I'm not so worried about her ability to do it as who might be 'helping', as when she decorated her room with some friends it was a right mess, which is all very well with your own room, but someone else's flat... She hasnt even told him- it is going to be a surprise! maybe that is what I'm worried about. I do feel a bit responsible, having helped her get the stuff. But its not as if he had made any effort to make it habitable himself, and she is supposed to have a room there. In fact he only got it on the strength of her supposedly living with him, and the letter I wrote for him. Anyway i expect I have said too much already. I was just expressing my anxiety at leaving her to get on with it. It's hard letting go, but necessary.
No wonder I'm tired.
