Thanks for your query.
I can understand your concern and the child's problem. However, it is not possible to comment about it till the skin condition is seen. I suggest that you discuss with your doctor the following:
1. Is it really necessary to soak in luke warm water for 20 minutes?
2. Can the ointments
be reduced in frequency so as not to interfere with the child's routine?
3. Can the number of shampoo, ointments be reduced to only one or two?
A via media can certainly be found out after discussing with the doctor.
I hope I have answered your query to your satisfaction.
