My son is 34 months old and going through the same thing. He asks for milk and he wants to come sleep with me. I started 3 days ago just telling him no and go back to sleep. It takes usually 5 min and the he is back to sleep. Last night he told me he wanted me to make him safe. I went in to see him, tucked him in and he insisted i sit on the end of the bed, i didn't, he freaked, then he said he had to pee, we went to have a pee and I told him firmly to get to bed and that was it. I will only let him have a pee and that is it. We tackled called backs at bedtime and ew the same way, a firm no and get back to bed. No more mr nice guy!!!! Things will most likely fall apart when we go on vacation but at least i know i can get back on track. be consistant it is worth it.
