Permissible and Impermissible actions in Ihraam

Underage child coming out of ihraam due to sickness

Q: We came on Umrah with kids and my 6 years 8 months old fell too sick that we have to take him to emergency in Mecca in the state of ihram. 

We treated him and then my wife and my daughter we performed Umrah Alhamdulilah. But due to his sickness we can’t take him for umrah and he had to be taken out of ihram state to take rest. What should I do? Is Damm or Sadqah wajib on me?

Wearing underwear in the state of ihraam due to urine incontinence

Q: My father has a small problem with old age and urine drops. He says straight after he goes to the toilet, about 5 or 10 mins after, he has some trouble with few drops. Then it subsides. 

He usually uses tissue with his underwear for a few minutes after going to the bathroom in case any drops come out and then discards it a short while later. 

He's concerned with ihraam and how would he manage. 

What would be suggested? Is there an option to wear underwear and pay damm? Or is there any alternative.
