So I wasn't sure if I should start this thread. Not sure if anyone will even see it but here goes.
DD2 has been referred for her delay in reaching out (in that she does not do it at all at 6 months)
She is so different to DD1 and people keep telling me she is just more:-
placid/chilled/second child. So smiley, so happy but very, very placid. Hardly ever hear her cry. So rare - that is till this evening. Went to supermarket and had to leave as she became truly hysterical. She was jerking her head and clicking whilst screaming in distress
not seen her like that before 
My gut is telling me something needs addressing but the few people I have spoken to have just said she is delayed and I am worrying unnecessarily.
Did BLW with DD1, DD2 showing no signs/not nearly ready for weaning...she is happy and content (in the main) so why am I fretting?
