5 is way too old. I think they would like them by 2
At two, they still may not be talking well, still sucking pacifiers, or not completely potty-trained. At two, some kids still like to be rocked to sleep or carried around when tired.
If the leftists wait until kids are five, most of those time-consuming tasks will have abated.
After all, leftist DON'T want to work too hard.
