LO has been very clingy lately and her sleep has become horrible (after improving).

She wakes up pretty frequently when in her pack n play and can only sleep longer than an hour at a time if she's sleeping beside or on one of us. She's also been sneezing more and sounds congested. She sounds like she's growling at us a lot of the time when she would normally be "talking" to us.

Her appetite is the same although she's spitting up more and she has no fever. She's not giggling as much but she's still smiling a lot.

Does this sound like a cold? We've been using saline and were going to try the humidifier tonight. Her mattress is also raised at an incline already. Any other suggestions on how to make her more comfortable?
