I work 3 days a week. Two days both my boys go to a creche, but the third day my mum has them. She comes and stays over on Monday nights (she's on her way now, with freshly baked scones!!) and has the boys at our place on Tuesdays. It's fantastic! My boys both love her to death, and nobody dares mention the 'G' word (Grandma) before she arrives or it's a hellish wait, with my eldest draggin us to the front door to check for her every 2 minutes. Mum also does as much around the house as she can, depending on the boys. She's done all my washing, swept and mopped the kitchen, changed beds, ironed, everything you can think of. She also has dinner weaiting for us on occassion!
I'm like you, i couldn't afford to have the boys in creche full time, so i found a balance that works well. Good luck doing the same!
