First of all, let me say how sorry I am to hear your sweeties are sick. I know how hard that is, from experience, on the kiddos ... and the Mommy!
Between the time my son was 10 and 13 months, he was VERY sick ALL the time! In three months, he had 9 ear infections (2 of those were double ear infections), RSV and walking pneumonia.
At the time, I worked full-time outside the home and he was our only child (he is now almost 3, and we have a daugther now that just turned 1).
We were at our wits' end (my hubby and I both) ... both of us had missed soooo much work to stay home with him, we were spending so much money taking him to the doctor (what seemed like every week for a long time), and we hated seeing our sweet guy that sick all the time! It was a miserable time for us all!
When he was about a year old, we took him to an pediatric ear, nose and throat specialist (ENT) to discuss tubes. They also tested his hearing to make sure he had not experienced hearing loss with all the infections he was prone to having. His hearing was fine, and the doc said that he was one of the worst cases (in terms of how many ear infections he had in a short amount of time). We signed the papers for him to have tubes put in his ears, but I also asked him about risk factors for those illnesses, as well as many others.
The ENT told me that boys are more prone to ear infections, as are pacifier users, but that his greatest risk came from being in full-time daycare. No one had ever said that to me before ... guess no one that knew me well wanted to make me feel bad about something I had no control over (or I thought so at the time). He told me that he guaranteed he would be 100% healthier in 3 weeks or less if I stayed at home with him and pulled him out of daycare.
For us, we just didn't think we could do it, but it broke my heart to think that I could actually do something to help my baby ... and we talked a lot about it and thought about our decision very hard. After a lot of thought and prayer, I quit my job and started staying at home with my son full-time 3 weeks later.
For us, we were spending almost my whole salary on doctor's visits, gas to my work, medicine, daycare, etc. And, seeing our son so sick just killed us ... the RSV was the sickest I've ever seen him, and just put us over the edge as a family!
I know LOTS of kids that go to daycare full-time, and LOTS of kids that stay home ... both with wonderful results. I'm not telling you this story to entice you to quit your job and stay home with your kids ... I know it's not something that works for every family (whether financially, emotionally, etc.) ... it was definitely the hardest decision I've ever made (and a huge adjustment for us all in many ways!).
I just wanted to tell you my story, and let you know that we were told they would outgrow a LOT of this stuff as they get older. And, to let you know that my son, despite all the illness and insanity that we went through when he was young, is a very healthy and happy toddler now! ;)
I'm just so, so sorry that you're having to go through this right now. I know firsthand how very hard it is to have a very sick child and try to juggle everything ... and to feel like you're losing your mind!
You and your family will be in my thoughts and prayers. I hope your children get better soon, and that you feel better, as well. Hang in there!
