I think someone is getting jealous

Last night Nigel and I talked about how we will have to get our cat Ty in a routine of not sleeping with us for the first few months while the baby is in our room. I woke up this morning with my arm completely asleep. I had that moment of panic where I literally could not feel my arm at all. Then came the sharp pins and needles that lasted a few minutes until I could feel the blood making its way back through my arm. What could have caused such pain.....
