Usually out of habit I sleep with my back to DH during pregnancy to protect LO and I.  Well, my little guy (the youngest other than LO) crawled in my bed in the middle of the night and at some point I must have turned over as he gave me a not so nice square kick in the lower abs (right in my uterus).  It hurt like crazy!  I'm ok but still sore.  Baby is still moving fine.  I have an ultrasound in two days so I'll be sure to mention it to my doc then.  I forgot that I used to put pillows over my bump while sleeping to protect me from this very thing.  Just wanted to let you ladies know so no one else gets whacked while down.  Trust me...it's not fun!
