I dont know if im asking for advice or just having a vent, i think ive had all the advice i can take right now, but who knows maybe someone might have a fresh idea

My adorable little 3 in march darling son, gets into everything, and i mean everything, i take my eyes off him for a second and he has done something wrong, he gets told off, and he looks at me so sad with these big blue eyes, and then goes and does something else, we have even smacked him, and to no avail, nothing works!

Mum suggested keeping him by my side at all times, taking him to the loo, even when i get off the lounge to get a drink he must come with, my husband has suggested a straight jacket!

So anyone on face book would have read as recently as a few minutes ago the latest of my sons doings..

Yesterday, he emptied a brand new full 750ml shamppo down the drain, while i was prepareing dinner, today he covered the back yard in my husbands brand new $30 pouch of tobacco and filters and papers, and just now not more than a few minutes ago, my oldest came home from a friends house, he was inside with me, my other #4 was in the shower i went to the balcony said good bye to her friends mother, went inside and the brand new replacement 750ml shampoo and the brand new conditioner bought today was gurggling down the drain, and he was wet!

He had gotten his step stool, used for washing his hands, put into the shower and reached up!

We have a lock on our fridge, which i forgot to lock yesterday, and he emptied out an entire salad dressing, mayo, custard and mixed it in water in cups, i had only left him for a few minutes.
I went to the loo, and he tipped a bottle of spray and wipe on the floor, which he used a kitchen chair to get.

We got a security gate for the hallway, so when/if he woke before anyone else, he couldnt go into the lounge kitchen dinning area and destroy it, and so far it works, unless #4 lets him out, then the two together are trouble.

The list continues on what he gets up too, and im fed up, he is super quick and sneaky, he opens a door and shuts it behind him, so u dont think he is in there, he loves to enter #1s bedroom and trash it, then she starts yelling and carrying on!

Reading this all back to myself, i feel broken, i cant take my eyes of him for a second, none of my others were really this bad, he is the youngest atm, and im tired, being pregnant and in the heat, i cant keep getting up and chasing him all the time.
