Waiting to hear from the doctor but we’ve had flu in our house and our nearly 9 week old has a fever and I’m just putting two and two together at this point. Any advice? I know there’s not a lot to do except Tylenol (as directed by doc), and monitor her breathing and hydration/eating/demeanor, and watching her fever generally but…any tips or encouragement welcome!

Hi, my friend just had a baby 2 days ago. Her oldest (21 mos) has been hysterically crying since being introduced to baby brother. Any tips/tricks to help her through the transition? I told her to put more emphasis on her being a 'big sister' and less about the baby.
