32 is way too many. Children usually only play with one or two anyway. Keeping some back for another day is great, but makes every day a present day. Ladytina42 is right about the short attention span too. I've seen that happen before.
Too many presents seems like a guilt trip for not having time to spend with children because of work commitments. Try giving memories instead if you want to spend spend spend. A trip to Lapland, a visit to Harry Potter or a football match or something else they're keen on. The up-front cost might seem incredible, but set against the amount spent on things that will be ignored, destroyed or discarded rapidly, it's not so bad, but it does involve more effort.
