My son is about 9 months old. He woke up this morning a little under the weather, coughing a little bit. The afternoon, he learned a new trick: he stood up in his crib. Right as I got to him, he fell down and bumped his chin . He cried, there was just a little bit of blood coming out of his mouth. Since that, I noticed his voice was a little hoarse. I don t know if this is attributed to him perhaps a cold since he was under the weather or if maybe when it was from when he bumped his chin. I plan on going to the doctor tomorrow, he is doing fine otherwise, he is his normal playful energetic self. Just would like to know what might be going on.
