I'm married and have a child what's the big deal?

I'm pregnant again just found out & told my cousin he made it sounds like the family would be upset & mad I had my first at 18 and I'm 20 now we planned baby #2! Why should my family be so upset & angry about a baby when they had babies the same age? I was told I'd give my grandparents had anxiety & I would upset them because I'm young & pregnant! I'm also married own our own home two vehicles he works and brings home pretty decent money! So what is the big deal in just aggravated that I can't live my life with out the pressure & the judgement of my family! 😓👿
