aww hun i feel you pain
we used to get stopped at the time becuase they were twins
and then i would get "OMG they are soo small!" like no crap sherlock (mind you they were 1.7kg and 2.4kg when they came out of hossy so that was big to me at the time)
and they i would be ask when they were born, were they sick and cop this - were they IVF? like i am gonna tell a stranger this info

I did end up with a leather hide from all the comments and i learnt not to make eye contact with anyone when i was out- i know that sounds strange but i was getting stopped like ever 100 meters and a 30 mins shopping trip would end up 2 hours cause of all the sticky beaks

In the end I would make sure that they were really covered up so they could see out but people could not see how tiny and also not touch them- yup people would touch them and i would go off!!
hugs hun and it will settle and you do learn to be really sarcastic when you haave to be lol
hugs
