"You'll have another one" ?

Christine • Rainbow baby boy born January 2017 🌈 after a missed miscarriage Dec`14, molar pregnancy Apr`15 and blighted ovum Feb'16
Every time someone tells me this, i want to punch them in the face. I want to scream and tell them my baby is not replaceable. I cant just go have another one and forget about my first one. How do i deal with this gracefully, without hitting someone or acting like a crazy person? Sorry for the rant...
