I've never had a sick newborn before so I'm not sure what to do... Lila has been very congested and a little wheezy since yesterday. She seems to be eating just fine, isn't running a temp and isn't fussy. The only thing that is a little odd behavior wise is that she's been very very sleepy and just has this glassy look. For my older kids I would just say it's a cold and let it run its course, run a humidifier, etc. but am I supposed to do anything differently because of her age?
