I use blueseal Vaseline in the morning then at night I use either coconut oil or palm kernel oil, and my baby's skin is fine, you can check his pic on my profile
Feed your baby well a d their skin will glow. Feed well to nutritious meals too, they will get the good nutrients from you. If no longer breastfeeding ensure you include fruits and veggies in their meal the skin will glow. If you CA afford body products like sebamed go for it. If not use what you can afford but ensure to feed them nutritious meal and the skin will glow from Inside out. For me I use palm kernel oil and their skin is just perfect. They started reacting to most skin products.
