3rd babe- when did you start getting big?

Da

I popped pretty early with first and second despite being tall- my sis is currently 25ish weeks pregnant with her 1st and I’m 4 weeks with my 3rd. I’m worried I’ll be bigger than her at thanksgiving when she’s like 9 months and I’m like 17 weeks 😂 here is me at 19 weeks with #1 on left and #2 on right I’m scared how big I’ll be this time
