I can't tell if she has just discovered that she can make a new noise or if its something else. She first started doing it yesterday when she was on the floor playing. I thought she was just getting excited maybe. Then today, she did it again after she had started fussing a little. I grabbed her and started rocking/walking her to sleep and as I was she was wheezing. Some pretty big wheezes at times. She has a doctor appointment tomorrow, but I'm really worried. Any ideas?? Me and SO just got over a cold, so I guess it could be that. But I breastfed her through the cold so I was hoping she wouldn't get it. She doesn't have any symptoms of a cold though. She isn't even acting sick.
