We have only bought J toys at three separate times: Christmas, birthday and once when he was about 6-8 months old and outgrowing infant toys like the play gym. We've definitely spent less than $100 on toys over his 17-month life.
I feel he's starting to get bored with what he has though and I think we should invest in a few toys that he will love for many years...
How often do you buy your LO toys?
