So.. I'm looking for some help. My three month old is kinda chunky (16 pounds) and has a couple chins. She doesn't get very much air up in her neck and her skin is getting very red and raw. I tried putting powder on her but it quickly gets absorbed and becomes wet-ish and chunky and sticks in her little neck cracks. She does tummy time to help air out the area but it's never enough. Is there anything else I can do short of going to a Dr.???? Also, what is the best remedy for constipation for her? Thanks for any help at all!!!
