They were doomed from the start by not being carried on Sky. Of course had they been, they'd have survived longer, but Carlton Kids would've probably eventually just been replaced by the CITV Channel, much like how Granada Plus closed to make way for ITV3.

By that logic Men&Motors would have closed when ITV4 launched, and yet it didn't. In fact it had a fairly major relaunch not long before.

Granada Plus didn't close because it didn't make sense for it to coexist alongside ITV3 either. It closed because that was the only way ITV could engineer a path to getting it on the Sky EPG from launch, in the era of there being a shortage of available EPG slots. If there was another way of getting a Sky EPG slot I don't doubt they'd have done it.
