One Sunday morning way back when, we sat on a bench at church. Isaac was about 18 months and I had him dressed so spiffy. The family in front of us had a little boy, about 2 or 3, who turned around to play with Isaac. Then it happened. He spewed, hacked, snot flying, sputtering through a long cough. I moved Isaac immediately. That week he got sick. Nasty cold. Then he couldn't breathe. So I took him to the pediatrician. Diagnosis:RSV. I said, "Hey! He's 18 months! I thought RSV was for tiny babies" No. Older babies can get it too. The RSV filtered through his little body and he developed asthma. For years we used a nebulizer each day to treat the wheezing. Every time we went camping, each time we were around fire, every day of an inversion, colds and coughs, grass blowing in the wind, playing with a dog, heck, just being around people who owned a dog, swimming, going outside to ride his bike. All of those and more would bring on an asthma attack. When Isaac was about 8 we put him on an inhaler and he began taking Singular. Wow. What a difference Singulair made. He didn't wheeze so much. It was pretty much being around a dog and environmental factors that got the asthma worked up.
