Shaving/Trimming the hair after performing a second umrah

Q: I performed my first Umrah and removed all my hair with a zero trimmer. After 2-3 days, I performed a second Umrah and removed my hair using the same zero trimmer (though the hairs were very few). I was in doubt as to whether it was correct for me to use the zero trimmer. Since I had a doubt, I used a blade when I made the next 3-4 Umrahs after that. Was it correct for me to use a zero trimmer or was it necessary for me to use a blade?

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.
