DS2 was dry during the day around his 3rd birthday, but not really clean for another year.
Since then 3-4 times a year he has had spells of several weeks when he has started soiling himself again. Not occasional accidents, but every day for several weeks. Then one day he'll stop and be OK again for months.
Until the schools broke up he'd been doing fine for several months, but as soon as he finished school he started soiling again and the only days he's been clean since were the 3 he had diarrhea (work that out!)
It does sometimes seem to be an attention seeking thing or a protest when he feels he's not getting his own way. I've been trying to be matter of fact, clean him up with minimum of fuss etc, but DH is ready to take a hard line and when he did it today made him wash his own pants. I'm not sure I like that and in any case DS seemed to enjoy it.
What can we do? DS2 is not at all embarrassed or upset when he has these "accidents"
