Hot and humid in Canada ???
What can I say then about our frying pan ?? LOL
On the +ve side, it is always great to see families having quality times in the outdoors.
Make sure you have enough contingency preps for the young one. Anything like a mosquito bite could ruin the outing. Also, depending on your area's wildlife, please do not role out completely the off chance of facing some nasty critter, and you won't be able to outrun it with the baby.
Being a paranoid dad, I prep for outings and trips by adding up plusses and minusses. I always add one minus for every dependent person (too young, too old , too sick ..etc. ) and one plus for every "capable" person. Too many minuses, I start thinking of other plans.
