Emily and Daya eczema

My Pastors wife, Emily, and their almost 2 yr old daughter Daya have really bad eczema. They have both been food allergy tested and have a long list of foods they cannot have. Some foods are different with both of them, which makes it very difficult for Emily to prepare food for the family. They also have a 6 month old son that will be starting to eat food so they are concerned he may have some of the same reactions.
Daya keeps having reactions in the church nursery so they think there may be some chemical skin irritation's also.
Daya has now started noticing the irritation and has begun scratching at the wounds causing a constant re-healing process.
Please pray for complete healing in Jesus name or answers that will make it less troublesome for them all to live with.
