When did you feel your second baby??

With my first, I felt her at 16 weeks and I remember the exact moment it happened and it was like little fast bubbles and it was very distinct.

I’m 16 weeks with my second now and I have felt SOMETHING but it’s not like the little fast bubbles, it’s more like a singular or two little tiny pokes here and there. So I’m like, is this the baby??? Or am I losing it. Like why don’t I feel the bubbles lol

When did you feel your second baby?? Did it feel different then the first?
