May i know why...

Oh, newborn skin can be so tricky to figure out! Heat rash, milk allergy, and product sensitivity can honestly look quite similar, so it's hard to say without seeing it properly. A few things I've picked up from other mums, if the rash is in skin folds or creases and your baby seems sweaty, it's often heat rash, which usually clears up just by keeping the area dry and using a really gentle cleanser. But if it's more widespread or comes with other signs like stomach upset or eczema patches, a milk allergy could be the culprit, and some mums have had good luck with products like Aveeno or Vanicream to soothe it. One neighbour also swore by giving her baby an oat bath, she'd soak oats in the water, and said it made a real difference. Honestly, I'd check with your baby's doctor or a paediatrician though, especially since you're not sure what's causing it, they can rule out allergies properly and make sure you're using the right approach for your little one specifically.

Hey mum! Newborn rashes can be tricky to pin down, heat rash, milk allergy, and product sensitivities can look quite similar sometimes. Heat rash usually shows up in skin folds or where baby's clothes are tight, and improves when you keep the area dry and cool; milk allergy tends to be more widespread and might come with other signs like fussiness or digestive issues. For gentle cleansing, most mums I know stick to plain warm water or very mild soap, and skip oils until they know what's triggering it, a few find that Vanicream or simple products like Aquaphor help calm things down while they figure it out. My neighbour brought her newborn to see the paediatrician when she wasn't sure, and they did a quick check to rule out dairy sensitivity vs. just irritation, which honestly took the guesswork out. It's worth getting your own doctor's take too, especially since babies' skin can change week to week and they'll know your little one's history best!

I think same as mine, u can check ur room humidity, since I keep my room humidity above 50%, with some air flow (can use fan) baby rashes start to disappeared
