I have just started doing this, I am a SAHM however DH is self employed so we pay him minimal wages. Therefore we have started making contributions for both of us, otherwise if business was to go down hill in the future we could be in big trouble come time to retire. We are not paying that much but something is better than nothing, and as the kids get older and I hopefully go back to part time work we will increase the payments.

I think it's a good idea if you can afford to do it!!
