Ive been lurking. So sorry to read all this Tess, what a massive bombshell, for you and dsd.
I just wanted to add my experience, as an ex childminder. Several posters have mentioned Care to Learn - I looked after a little four month old baby whose mother was sixteen, she'd sat her gcse's up until she went into labour..
She got her childcare paid by the charity, they paid me directly, so she didnt get the money herself, it solely pays for the care. She would drop him off at half eight, go to college and get back for around half three/four. She was a little chaotic, time keeping wise sometimes, but she was a pretty good mum on the whole.
In our area, we have a group of childminders who are experienced at caring for teenaged mums' kids, and have had extra training. They are excellent at helping with advice re. weaning/sleep/ all the other challenges that we parents face. There is also the option of moving schools to one with a creche - there are two or three upperschools here in bedford I can think of with this facility, that both the staff and the students use if they need to. I think it would be a good move now to start thinking about childcare, and making concrete plans. When dsd gets a bit futher along, go with her and visit them, help her think about questions to ask, make it crystal clear that you will not be providing the childcare. I really think that if you do end up doing the child care, it will put a massive strain on you all. If she takes responsibility for this, and finds somewhere that she can drop off to on her way to school, yes she will have to get up early to do that, but it is perfectly possible and something she should do herself. I think. good luck
