Hi all, can descibe how does a baby's movement feels like? Week 18 now and wanna prepare for it.

At first I also didn't understand what bubbling but when it finally happened you'll get why its called bubbling lol. I don't know what the baby did that cause this feeling but yeah can feel a bit of twitching? Movement? That's not caused by our normal body movement. As weeks goes by it'll become stronger. At 31wk now sometimes I cannot fall asleep because baby keeps moving at night lol.
