Trimming one’s hair with a machine after performing a second umrah

Q: After completing my first umrah, I removed all my hair using a zero trimmer. After 2-3 days, I performed a second umrah and again removed my hair using the same zero trimmer (though the hair was very little). I was in doubt in regard to whether I did the correct thing or not by using a zero trimmer. Is my second umrah valid as I used a zero trimmer? 

Undergoing trials

Q: My baby has been having seizures since birth. He has brain damage and other complications. Doctors are perplexed by his problems. His brain mri shows damage but not that much. Still his seizures are persisting despite taking 4 medications twice a day. Medical science is not able to say with certitude what is making him having these seizures (infantile spasms). My baby is 16 months, doesn’t move, doesn’t talk, doesn’t swallow properly, no neck control. I am so so down. I cry with Allah everyday for my child.
