My 15 months old baby's lips getting darker and dry. Any recommendations for baby lip balm?

Hi Sis, I didn’t really wipe my little one’s lips with wet wipes every time after milk, I usually just gently dab if there’s obvious milk residue so it doesn’t sit there too long and irritate the skin. For dryness, I found it helped more to focus on keeping the lips moisturised with a baby-safe lip balm or even a thin layer of petroleum jelly before sleep, especially if the room air is dry or aircon is on. For darker lips, sometimes it can also be from constant dryness, saliva, or even friction from wiping too often, so I would be a bit gentle and not over-clean. If it doesn’t improve or you notice cracking or irritation, maybe just check with PD to be safe.
