I had the same problem when my daughter was that age. She's now three. My son, who has Down syndrome and therefore, a suppressed immune system used to catch EVERYTHING... we spent more time in the doctor's office than they did at school!! It was horrible. A lot of mom's I know use Juice Plus for their kids with Autism due to limited diet and immune issues and I had heard about it for a while but never really bought into it. Finally, after a year of absolute hell with illness after illness and ear infection after ear infection, and tired of snot being on everyone and everything... I finally tried it and I have to say, it has been the best investment. My son and daughter have been on it for over a year now and my daughter has not been sick one time! My son has caught one bug and it took him way less recovery time to get over it. I take it too since I also have another daughter and with 3 kids and working as an occupational therapist, I do not have time to be sick and I definitely feel better. Juice Plus is a whole food based product. That's it. nothing else is in it. So basically, it is the same thing as if you ate all the fuits and veggies you were supposed to everyday, imagine how healthy you'd be... that's all Juice Plus is. It cost 22 to 40$ per month depending on what you order..... which is a lot less than co-pays at the dr.office! They come in gummies, chewables, or capsules (you can break open and mix them in anything..oatmeal, milk..whatever). My kids do the chewables. I use the capsules. I hate to sound like a sales person, but it really has made the biggest difference in their quality of life. I've just started my youngest (12months) on it as she has a lot of food allergies and a poor immune system too.
Another therapy we use that has helped my son with Down syndrome with ear infections is craniosacral therapy. It's a little on the crunchy side as it is considered an alternative therapy, but we've seen great things with it. we use a guy named Ken Piercy in addison. www.kenpiercy.com
If you're wanting to travel more of the medical route... you might check out a pulmonologist (Dr. Andrew Gelfand is fantastic) for all the respitory issues. Or an allergist (Dr. Robert Sugarman or Dr. Wasserman in the same office are both great) or maybe a GI dr. since that's where your immune system is most involved (we like Dr. Kendall Brown). You might also seek guidance from a nutritionist (Faye Elahi is great)
If you're interested in more information about the Juice Plus let me know. Being a pediatric therapist, I know a lot of moms who use it and love it and have experiences similar to mine. I heard about it when my son was 2 but was skeptical... 4 years later I finally bought it and I so wish we had started it sooner. Now the only thing we go to the dr. for is well checks annually.
