During the June, November & December holidays, I become temporary stay at home mum.
My days usually quite free in the morning when my boy goes to school. I read, surf net, watch tv, watch DVDs, etc. Arrange for my tuition to be in the mornings.
When he's home in the afternoons, I play with him, read to him, sing with him, teach him new things.
Actually if I have a 5-yo & 7-yo, I think I'll be very busy teaching them or preparing materials to teach them. Crucial age to build a strong foundation for their studying career. If you are getting bored, can try surfing online to check out free resources you can use to teach your kids I enjoy doing it alot
