My two year old loves Glen Tanner (nr Aboyne). A number of good signposted walks over the other side of the river from the car park.
There is also Burn o'vat near Ballater. Good paths and if you have a backpack for carrying the toddler, the walk up and through the back of the 'vat' is good so long as it is dry and no snow / ice as you have to cross the river a few times.
Glen Callater near Braemar. Taramac road to start with, lunch at the bothy next to Callater lodge and you can take a wander further up Jock's Road depending on the buggy.
There is no really child friendly places to eat in Braemar but the Italian in Ballater (La Mangiatoia) is pretty good.
Cruxter, good that you carry all that kit but given this situation, where would you have used it? He was in a gully that had just avalanched (cornice collaspe). This gully has two exits so who is to say that the second cornice is not about to go too?
If you get out of the gully you are then in the firing line for the next gully which is a known avalanche hot spot.
In this case, the nearest safe place he could shelter was the first aid box. Even if this box was locked*, safe shelter can be had at this location.
All credit to the guy for getting himself to a safe position and waiting for rescue.
* - The Lochnagar First Aid Box has had items stolen from it in the past (100m static IIRC) but remains unlocked.
Red Squirrel in Glen Coe. It was a dive last time I was there, made all the worse by the realisation that the river lever was higher than the campsite and only held back by what looked like a homemade embankment.
Went wild camping in Glen Etive. Living on the east coast we failed to realise it was a Glasgow holiday and half of said city was camped in Glen Etive. One weegie even pitched his tent on an island in the river and come morning was driving golf balls off it towards the far bank.
Took my folks wild camping in Glen Nevis. Planned to walk through to Steall and camp there. Stopped at Glen Nevis bar, mother dissapears and comes back saying she has phone the Glen Nevis Campsite, there are spaces and she has booked us in. Good facilities but it changed the whole feel of the weekend.
