Re: Can congestion be related to an allergy?
Talk to the pediatrician. Congestion can certainly result from allergies, but you're not likely to figure out what, if anything, your LO is allergic to just by guessing. I never in a million years would have guessed what my kids are allergic to. It's a big old world and there's just too much stuff out there.
Another possibility for congestion could be adenoid or sinus issues, so that's another thing your doc could offer perspective on.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
