Is your husband willing to document this and take it to court? Medical neglect is pretty serious. Or does he just want to keep feeling helpless and lamenting about it to you?

I am confused as to why she would go to the ER when she is against "modern medicine"... what does she expect them to do? lay hands upon the child???

My SD is 19 now but she developed juvenile diabetes at about 11.  Her mother, North Korea, is also a believer in alternative and holistic medicene.  My SD almost died because of North Korea's incompetence.  She was very, very, very sick.  She went from 100 lbs to 68 lbs.  She lost 11 lbs in one month.  North Korea kept taking her to the chiropractor for spinal adjustments.  She's give her vitamins but no real doctor.  I was just having the worst fights with her father because he would do nothing against North Korea ever at all even that Christmas when he had to carry her like a baby up the steps to her moms house after eating lindor truffles that she got as a gift xmas morning.  I finally figured out what it was around January.  It just clicked.  We didn't get her very often.  But we were going to have a birthday party for my DD and she drank every single drink that we we had for the birthday party.  and then they went to go get Chinese Food and she asked for a 12 pack of chocolate yoohoos from the grocery store next door and was drinking them hot in the car.  Her dad told her no and she was just crying cause she was so thirsty and a light bulb clicked in my head.  All the symptoms made sense.  So I made him call North Korea and I sat next to him and she said, "NOPE.  Her sinusus are just really dried out."  Her mom had full medical rights and he just had every other weekend (maybe).  So my mom is a pharamcist and I was working on getting a blood monitor to test her blood myself and force her dad to act when North Korea called perhaps a week later saying SD was on the way to the hospital in am ambulance.  She was there for over a week and diagnosed with type 1 diabetes.  Even now its the same old fight.  Her doctors think she should be on an ace inhibitor and North Korea says no, that she knows best with her cosmetology license over any doctor.  I had a heart to heart with SD when she turned 18.  I said , "You are in control over your own health now.  You get with your doctors and you get educated.  It's your toes and fingers and kidneys, not your moms, and you'll lose them if you keep listening to that fool woman."         

This is insane. She took her to the ER for fricken hives??!!

Im allergic to MY dogs! (Who also sleep in our bed) Guess I need an ER trip everyday!

I've built up immunity to SOs dog he had before me. My lab am not as allergic too but, if either one of them lick me or scratch me I get hives and they are gone within the hour. 
 

I've dealt with animal allergies and seasonal allergies my whole life. 
 

If you guys pay for these absurd ER visits I would stop. The doctors must think they are insane. 

that triggers allergic reaction, to the point of hives, reflects all that well on your parenting.  Another poster noted the risks of continued exposure, that reactions can change over time, to become more severe.  While BM certainly was wrong in her approach I am not sure that defaulting to medication is the best plan either.  Does SD have other allergies as well?

and for what it's worthy no medication is completely safe.  I was recently in the ER due to an allergic reaction to Benadryl.  I am 59, have taken it off and on for years and was taking it as prescribed due to poison ivy rash.  It was a miserable experience and honestly scary.
