cough in 2mo old

So I've noticed this little cough in my two mo old that just started when we got to SC night before last.  Noticed it when we were in the car. It was very small. Didn't have it all day yesterday. Then this morning fed her no problem then when I went to burp her she started again and it got worse for a second. Tried to put her back down and as soon as I did she got it again kinda bad for a second. No fever. No runny nose. Not sure what to do as we are out of town.
