Chapped/blistered lips?

Ma

The doctor didn’t say anything about her lips at her two week appointment three days ago. I asked the Red Cross nurse on the phone about it after reading many different sites about it. She said that I should put the humidifier on in the room at night and her lanolin on her lips.

Do you think there is another issue though? Like a tongue or lip tie? She’s definitely not dehydrated. She’s gaining weight like she supposed to and eating for an average of 20 minutes every three hours. She had it a shallow latch when we were in the hospital when she was born. It was corrected through a nipple shield A few days after coming home from the hospital.
