I think DD has one. Her equilibrium seems to be off and she's telling me her ear "feels all blowy," which makes me think she's got some fluid build up, possibly from an infection. She also has a really plegmy voice to the extent that I could barely hear her when she was trying to talk this morning.
I tried to get her to let me put some EBM in it, but she wasn't having any part of that. Other possibly important info - she isn't nursing anymore, and won't drink EBM, she hasn't eaten much in the last few days (she's usually a big eater), doesn't have a fever, she's three years old, she is unvaxed, and she hasn't been to a ped since she was 2 months old, and she doesn't have a primary care ped. Thankfully, I do have a good ped for my 9 month old (he was preterm and had RSV at 4 months, so we do WBV's for him to keep on top of potential issues!) who is no vax friendly and open to alternative treatments. I just don't know if a visit is necessary or if it will clear up on it's own. I'm just worried because I had a non-painful ear infection a few years ago that got really bad (to the point that I couldn't walk across the room without falling down and vomiting) and it took, literally, 2 months to clear up enough (even with meds)that I felt okay to even drive (looking over my shoulder caused me to get so dizzy that I felt like I would pass out). Anyhow, none of my kids have had one before, so I'm not sure of the point at which treatment is necessary.
