Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that your daughter is suffering Chapped lips leading to making them dry and cracked.... In toddlers it is commonly due to dehydration, lip licking habit, excessive dry or cold weather etc.. I would suggest you to start applying thick coat of petroleum jelly over the lips and do it frequently throughout the day.. It will help in locking moisture and prevent dryness by providing lubrication.. Beeswax containing lip balm is also helpful.. Avoid excess sun exposure or exposure to very dry and cold wind.. She should drink plenty of water.. Do cool compresses over her lips.. In case if there is no resolution in a week consult a Paediatrician from the lips to check for infection and treatment can be done accordingly.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
