Little sod (13m) is being intentionally naughty...

[BeyondLimitsOfTheLivingDead]

He keeps opening the tortoise tank and taking down DVDs and opening drawers and playing with the buttons on the side of the TV, and moving the surround sound speakers and playing with wires and plugs and everything he shouldnt! He normally listens to "no" and is generally good as gold, so I've not really had to deal with this before!

Now I'm not well (not quite flu and pregnant) and he's being an absolute nightmare.
I guess he knows I'm not well and is playing up cause of that?

But what do I do?
I move him away and 10 seconds later hes back doing something he shouldnt

WIBU to put him in a cage?

Normal normal normal!

My 12 month old is much the same, her favourite trick of the week is to stand by the side of the tv, hang on to the curtain and purposely fall backwards (into the wires etc behind the tv)

My cupboards get emptied at least once a day.

I have to barricade the TV on/off switch with a nest of tables and a toy box.

Why oh why do they seem to have a homing device to the things they aren't allowed?!

If I say no, she looks at me and shakes her head.

She's cute. She's funny. She's infuriating!!

My 14 month old is the same, loves anything "forbidden". I have a kitchen cupboard that he can raid, some books on a shelf that he can juuust reach (so he feels pleased when he gets them down), and,to be honest, we go out between 11 and 3 every day! Swimming, park, friend's houses, park, swimming again, soft play if I"m desperate.

NORMAL! He is exploring. Just let him do it. Tidy up once a day. (Preferably just after he has gone to bed)

They do this for ages. Considering you've got another baby on the way, you are probably looking at around three years of toddlers fiddling with your stuff. So, rather then thinking of your dcs as sods, YOU need to take responsibility for your things. Move the things you care about out of reach, give them a bit of leeway with the rest, and put a bit more effort into entertaining your d.
