Are you sure your not talking about my 3 sons LOL
This is UNfortunately normal
I moved my sofas because i was worried they might fall over the railing and down the stairs,
for the most part mine are OK and able to balance and things,
but i still keep a close watch,
as for the tables, if they climb on the counter or tables
BED TIME, this is dangerous and just plain BAD idea
I say get down right now, and then point to their rooms and then put them to sleep,
till they stop crying,
This is what a do for every BAD behavior or act.
throwing, hitting, mess making( more than just average)LOL
As for climbing out the crib, it will happen as soon as you see him lifting is leg up to the railing, you know its gonna happen.
LOWER it to the lowest setting , and if he starts climbibg out,LEave the railing DOWN, its safer than being up high, Pack-N Plays are usually more difficult to climb out of.
This is a hard stage, but it does stop eventually.and toddler beds are sometimes easier. if not safer.
Never heard of a crib tent, but they sound pretty good.
My boys would just play in it tho and probably break it, and could certainly unzip it,too smart for their own good.LOL
