Almost 7 month old not laughing as much

Hey!

Did anyone else’s baby become harder to make laugh as they get older? Mine still smiles and will giggle but getting that full blown laugh is proving to be harder these days. She’s ahead with physical milestones. All others seem to be right on time. She was born 3 weeks early. She used to laugh pretty easily but seems to be more stoic these days.

Should I be concerned? My anxiety around development has been a little wild. (Talking with a therapist about it). I work with students who have extensive needs but appear physically “typical”, I hate to say it that way I just don’t know how else to say it.

She’s vaccinated as well. And I know it’s the right thing however I find myself being anxious about that as well. Having a hard time rationalizing.
