DS is also a march 08 baby and we are currently having this discussion.

Lot's of people I know are keeping their LO's back. Some have had similar reasons to Divvy, for example if they want to do Hospitality it can be a bit difficult when they aren't 18 yet. I was born in march and so was OH and neither of us were held back so I was surprised that most people do now and I honestly didn't feel disadvantaged in year 12 not being 18. In fact seeing my cousin, who turned 18, in May in year 12 scares me more as she can go out whenever she wants to the detriment of her HSC year

I think it is an individual thing but I am 90% sure that DS will be ready to start kindergarten (primary school here) in 2013.

It works a bit different in NSW and I had his name down for a preschool for 2012. He is currently going to long day childcare 3 days a week. I was offered 2 1/2 days at the pre-school next year and they won't offer me full days until he 'has' to go to school (ie, starting primary school in 2014 when he would be turning 6) but IMO it just isn't worth it. I know he learns academic stuff at pre-school but it's only 1/2 days and I think he will get a lot more from being at childcare where they do 'emerge' learning but not in such a structured way as pre-school.

Anyway that's my 2 cents worth
