Coughing or learning to laugh

Nobelungu

Mamas, I’m not sure if my daughter (3 months tomorrow) is learning to laugh or has a cough. One moment I’m certain she’s learning to laugh the next I’m not so sure. It’s like a cough/laughter that she only does when she is playing and being her noisy self (she screams and smiles a lot when excited) when I pick her up and just sit her relaxed on my lap she stops this cough laugh. She doesn’t do it at any other time just when really excited and playing but sometimes it really sounds more like a cough 🧐

Also when I laugh back she is almost shocked and looks at me intently.
