My almost 8 week old son woke up not too long ago and his cry was very hoarse and weak and he nursed only a few (less than 5) minutes and was back to sleep. He has been sleeping all day and has not been nursing like he normally does since last night (yesterday was my first day back to work and the first day of being away from him.) He was also super congested and I had to clear out his nose. Anyone else experienced this with your babies? Let me also add that he has NOT been running a fever of any kind.
