My son swallowing pills

I was in the house I grew up in (floor plan identical) with my mother. She and I were arguing about how much money I owed her. It was a very heated argument which is very odd for us. She was saying I owed her more than I thought I did. I was trying to get ready for high school at the same time (though I felt like an adult in the dream) so I went into the bathroom to brush my teeth while still arguing with her. Once I was done in there I figured I should check on my 23 month old twins who had been playing in my parents' room. I opened the door to the two of them walking around the room but I realized that my son had a mouth full of pills from a prescription bottle he found on the night stand. I grabbed him by the back of the neck and I could feel all of the pills down his throat. I woke up out of breath.

Another falling building

I was in a skyscraper that started shaking and fell over. I don't think I was with anyone I knew.

Losing Jackson

I was riding a bike with my 22 month old son and daughter. I think my daughter was in a seat on the back but I was holding my son. I wasn't able to control the bike though so I put him to sit on the bar. I was surprised that he was able to stay there without falling off. But then I needed to stop and he ended up flying off the front.
I knew I needed to put them both in a seat on the back so I was scrambling around to get the seat set up. We were in a cafeteria sort of place so it was crowded with people. Jackson somehow got out of my sight and then I couldn't find him. I believe my mother was there so I left here with Madison as I ran out a door to see if I could find him. There was a stairwell and a door to outside. I ran up the stairs a bit screaming his name. I realized he wasn't up the stairs so I ran out the door to outside screaming his name mostly in the hopes that someone would hear me and help me find him. I was in such a panic that I would never see him again. I'm pretty sure I found him but I don't remember it specifically.
