New year new nickname for me 
But not so sure about the usual routine. The DSC decided to casually announce on the last day they were with us that the usual bus they catch from their mum's (5 miles away across very cogested town) to school (near us) is being axed from the start of the year, meaning they now have to catch two separate buses, or a different one that stops a mile away from the school and is apparently usually full at rush hours meaning they can't get on it.... First we'd heard of this 
The possibility of them staying more with us has been muted for ages, but never really resolved. DSS (17) is saying upfront now that that's what he'd prefer, and seeing his mum at weekends. It's hard to get out of DSD (15) what she wants as she tries too hard to second guess what you want her to say. She was struggling with the slow bus ride last term but just kept staying lots of extra nights at minimal notice, or even just turning up on the doorstep, without making any official change to her routine. Neither of them appeared to have had a proper conversation with their mum about the bus changes. Anyway, we sent them back with instructions to have a proper conversation with their mum and agree what they wanted. They said they'd decided to give the new bus a try for a couple of weeks, but two days into that DSD was texting saying could they both stay over the whole of next week because the bus was awful. DH has said yes, and I've said that's OK, but that we need to work out in the long run what's going to happen.
So next week instead of just my own two teens in my home, there will be 4. And the week after that, who knows? I get on fine with the DSC but really don't like not knowning what'll be happening. The odd night here and there is OK, but actually moving in means a whole differentn kind of parenting, which I don't think my DH really appreciates.
Where are you off to on your holidays Matilda?
