help! toddler driving me mad

so my boy has just decided he knows how to climb out of his cot the problem is he ends up in my bed at 1 ever morning......he is a very active sleeper and with me being pregs i cant sleep........the other prob is that i have the baby crib etc in our room ready for the new bub and im concerned that ty wont snap out of it by then..........he also wants to watch his movies in there wraped up in bed...this is also how he goes to bed.......im guess ing all this is to do with the heat as he is a very big boy but im going nuts............if he keeps it up then where do i put the babby? he also refuses to go to sleep during the day and gets VERY moody like anger managment styles and hits his head on anything....when i put him in the car he falls straight to sleep..........if i could afford petrol i would do this every day .

Could you put a gate across his door so that when he does get out of bed at night at least he can't come into your room? You would obviously have to get up to put him back in the cot but if he can't get to your room maybe it will stop the habit/behaviour after a while?

during the day before he is due for sleep he has an iceblock and he is a waterbaby so jumps in little pool and he is always running around half naked i spent literally all night one night putting him back into bed and a gate isnt an option as he climbs over everything last night we put him to bed with a sheet and nappy and he woke at 11pm screaming and this was with the fan on too..........hubby went to grab him but now the big sh*t has lost the plot and is way to over stressed that he yells at the little sh*t.........so kicked him out of room last night after 30mins of screaming i put polar express on and ty fell asleep within seconds i had to wake every hour to push him away from me though casue of the heat.............he didnt go down this morning and threw a wobbly for 1 hr this morning.........so i decided to leave him to it he finally came up and hugged me and not 10mins ago he fell asleep on the floor so put him in the single bed and gave him half a bottle cross fingers it last longer then an hour................normally if i get too exhasted i will take him to nana and pops but they have been away and are due to fly to oz next week so we arnt in a happy place

yeah he has both and he puts them into bed with him wherever he is..never leaves home without them.

yeah hubby has gotten up to ty since birth as this was the arrangment....if i get him he will Definatly not go down as he wants me to hug him all the time........was talking to docs today and she seemed concered and told me to take him in for tests............his rash is way weird which could be affecting him behaviour.........last night he slept all night in the singe bed ...yeah for us...........but day time at pops today was dramas........he screamed so much he lost voice and even poppa was scared...........put him in car and he fell asleep within minutes.
