worst. mom. ever!

went to dinner with the family....my 3 year old was being his usual self which led to him falling straight back on his chair at the restaurant. he cried, i held him...all was fine. fast forward 4-5 hours where he starts vomiting in his sleep. i think possible food poisoning or stomach bug. it was ~different~ though, but i couldn't put my finger on it. next morning after some much needed sleep led to a little clarity...i REMEMBER the fall and realize he quite possibly has a concussion! awesome mom that i am didn't even put the two together. after a frantic call to the dr i am quite certain that he did in fact have a concussion, but thank GOD...he seems fine. we had to wake him every 2 hrs last night and will continue to watch him the next few weeks. all i could think about was that natasha richardson who died a couple of days after her fall. i really feel like the worst mom for almost missing this!
