Toddler bed and night wakings

Ke

So I previously posted about how my son climbs out of his crib now. He woke me up in the middle of the night. So we switched him to his toddler bed because we will need the crib for the next baby, anyways. Well, he sleeps just fine in the toddler bed, he likes it and seems comfy. Prior to climbing out, he'd sleep the whole night through with no problems. But now he is sneaking in our room twice a night. The first waking, I will wake up to him and my husband puts him back in his toddler bed. But the second waking I must be too sound asleep because I find him asleep in the dog bed by the foot of our bed when I wake up. It's adorable, but kinda sad.... Lol. He tries so hard to sneak in and just sleep in the dog bed to be near us 😥 any advice? We used to bed share when he was a baby, I really don't want to revert back to that, I'd like to stay consistent. I'm nervous for baby sister to be here as she'll be sleeping in bassinet besides me and I know that will make him want to sleep with us. I feel bad forcing him back to his own room all by himself. 😥
