I'll preface this by saying I have health anxiety around my DD
She's nearly 5 month old and doesn't laugh. We've had a couple of goofy sounding exhales during smiling but no belly laughs yet. Lots of big smiles, eye contact and babbles etc.
My gp wasn't concerned. HV just told me to make sure I interact with her
But I'm worried, all the guides say laughing by 4 months (I know, I know, I shouldn't read them) Any other posters have children of similar age who haven't laughed? Is this a concern?
