I can't see it as well. When the tech did my babies ultrasound and checked for it, he said it would look like a black line around the babies mouth. Like Spade asked, is there a reason you're concerned your baby has this?
I just watch the video. I would say no. The lips look fine to me.
Doctors and technicians are the best people to answer this question. If nothing was mentioned by those individuals your baby probably does not have a cleft lip.
Is there any particular reason why you are concerned your baby might have this condition?
