Pee question

I just went to pee before bed. Washed my hands And was looking in the mirror and felt like there was still pee inside my urethra. So I sat back down and more pee came out. I finished and left and checked on my 3 year old and I felt it again and more pee came out and I feel it again Already. What could this be? It only feels like there is pee right in the opening of my ureathra.
