My 1 year old son is very active, and changing his diaper is increasingly difficult. I've seen temper-tantrums from some other children we know, but they usually stay put. My son arches, flips and actively tries to crawl away. These are things my wife and I have to do to get things done:
- talking to him (perhaps obvious).
- distract him with toys, books, things above him--we have a mobile in his room.
- do most of the work standing up, i.e. undress him.
- pin him down.
Pinning him down is a last resort, because it aggravates the situation. But sometimes it's needed. I should say, we are gentle, and he's just upset over being restrained.
House hold objects ("forbidden things", e.g. cell phone, paper/wrappings he might eat when unsupervised) are sometimes employed too.
Is there anything else that can be done?
My son knows the word "No", but he's only starting to respond to it as I intended it.
