Momsh, I know how scary yan, pero please have your baby checked by the pedia again right away or go to the ER kung parang lumala pa, especially with blood involved. Hindi kami doctors kaya we really can't say kung normal lang yan or kailangan ng immediate help.
What I can tell you is a few of us mums had similar scares with our babies' cough and colds, pero palaging better to get checked twice than worry the whole time, di ba? Trust your gut, kung parang off pa rin after the pedia visit, you can always get a second opinion. Sending you and baby hugs.
