I'd be interested to know how many hours you work if you are a resident single parent? How do you fit everything in?! particularly if you work full time. and by everything I don't mean housework but I mean things like helping dc with homework, after school activities, play dates etc etc, or do those things mainly happen at weekends. Next year my dc will be 7 and 4 and in ASC 2 days a week and my mum will help with pick ups 2 days a week but i wouldn't really want to ask her to help the dc with homework etc asides from reading.
FWIW my kids' dad is around but i learnt right from the beginning not to depend on him for childcare so i can work, plus he does shifts.
