I will be looking after DS and DGS who are very close in age for two days a month. I am looking forward to it very much but would really appreciate any advice or ideas from experienced childcarers. It won't be quite like twins or like two one year old mindees but I'm sure any practical tips will be invaluable.
We will be at DDs house. Unfortunately we will be spending most of our indoor time downstairs and the loo is upstairs, I will have to restrict my coffee intake 
. I'm wondering if I can get a travel cot into the bathroom and put another downstairs.
Just to give you a brief picture, both boys are on the verge of walking. DGS has washable nappies so more changes but he does stay still unlike DS! DGS has two naps, DS one. DD has a great double buggy and suggested going for walks to get DGS to sleep which will work well for both as long as I can get us all out of the house twice. I can just about lift and carry them both at the same time but not very far, I've used slings a lot with DS. DS spends a good deal of his day scampering about at a fast crawl climbing or attempting to climb anything in his path. DGS's favourite thing is being walked holding both hands. They are a great team when faced with a pan cupboard :)
(I'm also wondering about becoming a registered childminder but that's another thread).
