I am doing a PGCE with DD1 in full time reception and DD2 in full time nursery, which she only started as I started the course, so that was fun.
I have a DH who works split shifts so he can pick up DD1 on occasion, otherwise I depend on my lovely friend who walks DD1 into breakfast club and then picks her up afterwards. School has no afteschool club which is massive PITA. I am also lucky that DD2's nursery will take DD1 on days when school is shut but I have to work (inset, or election for example)
Mine is full time as well, with uni days 9-5 and school days 9-4ish so it's a bit manic but I am coping okay (although not got final essays in yet...)
I have a lot fo work to do out of uni but made it a rule from veyr early on to do no work while DD's were up, so I would get home, do tea and bed and then study for 3 hours. This mean no time with DH so I try and do less in the evening and have a morning at weekends if I can.
I take every spare minute of time during the day to work, my mentor said that they could tell they had never had a student with kids before as I am working every luncha dn breaktime to save me doing it later!
The house is a complete shit tip though, i mean, it was never perfect but now it's disgusting. The girls don't seem to mind though, on a few occasions I have been abel to pick DD1 up from school or pop into assembly type things ahs has helped. They understand when I am working not to disturb me, or that certain things are mummy's work and Must Not Be Touched
My tips woudl be to tell everyone you are studying, whether it is school, so they know if you forget stuff (DD1's school has been brilliant about me being absent minded), uni, so that childcare issues aren't a shock (I was allowed to take DD2 into a 121 with my tutor as she had been vomiting and couldn't go back to nursery for 48 hours) and your fellow students so they understand that you can't do all the social stuff but aren't a boring git!
The other students on my course have been fab, helping me out with ideas/research when I have needed it. And other mothers at school have been brilliant with lifts/drop offs/having dd's for tea when I am desperate.
In short (hah!) it is doable, and I find that, although loads say 'ooh, I don't know how you do it' you can prioritise a lot better than the younger students. After being a SAHM for 5 years I especially like the chance to have lunch at uni with grownups who have no kids and discuss grown up things, it's like a massive novelty to me. Good luck!
