Hi S.,
I had a similar problem with my son yet I felt that even after the tubes were in, we would still have the issues of the antibiotics and upper respiratory stuff. Fortunately, life presented an introduction to a Homeopath and the results were like a miracle. After the first remedy, his nose started clearing overnight and within a few days he had nothing going on...a few days later a fever, then another remedy and then after that, not even a cold for over 5 years! This after 6 months straight of being sick and many different antibiotics.
That was many years ago and since then I've learned a lot about many factors that contribute to our health both from being a mom as well as the things I've learned in my holistic coaching practice.
I look at many aspects now including, food allergies (which can energetically be rebalanced), blood type diet as well as what's called the PHS (Personal Health Strategies) obtained from 'The Human Design System' which identifies genetic imprinting from birth info (time, date, place) that can direct you to what foods are best or how they need to be taken in, as well as other strategies that align with the chemistry of the body and how things impact our health. There's also healthy sleep patterns that can be identified within each one's design amongst how many other things. Sounds bizarre but it's amazing information and very practical.
Some other methods of care (although I've not tried them myself) include salt rinses for the nose and vicks on the feet to clear congestion.
I would encourage you to trust yourself. The tubes may be the way to go or there might be a different alternative that's best for your child. Nothing is a be-all for everyone.
If you have any questions, you can e-mail me or you can find out more at themythandmysteryofyou.com.
Wishing you well!
S.
