Yes I would try

My kids have had 2 - 3 days daycare since they were 11 months old - when I was preg with DD (#2)- I kept DS in 2 days a week the whole time I was on mat leave and I think it helped keep a bit of normality for him too.

This time DS is at school, but I will keep DD in 3 days a week until the dust has settled after #3 arrives and then drop her back to 2 days. I need to keep a spot for her for next year when I need it for July and going back to work part-time if plans fall into place. Also, I figure I had 1 on 1 time with #1 and #2 and want the same with #3. And like you, we can afford it luckily with paid mat leave and baby bonus etc.

1 day is a harder transition I think - but depends on your child too.

I remember when I first went looking at centres and all kids seemed to have runny noses etc - but it hasn't been too bad at all (except for conjunctivitis - I HATE conjunctivitis) ....

good luck!
