Kate • 19. Married. Mama to a little boy 01•22•15. Military wife. CA.
Do any of you mommys that have a crawler know how to help carpet burn/rash on the knees and elbows?? My son (almost 10 months old) literally army crawls aroud the house and he has a rash/burn from the crapet and both knees and both elbows, and i keep putting lotion on them to help with the dryness and cracking but his poor little legs and arms look like they are sunburnt all the time! Any ideas are welcome! Thanks in advance!
