My 3rd child had tubes inserted @ 8 mos after 3 mos of recurring ear infections. Let it be known that her infections were tough for me to pin point as her sleep wasn't badly affected by the infections....so different than my 1st child & a little different than my 2nd. My 1st would wake up screaming with them & my 2nd showed clear signs of being sick (junk from the nose, etc), but my 3rd just seemed "off" but still pleasant & just a little bit affected through the night (it could've been a wet diaper or anything that woke her up, right..? And, she'd go right back to sleep).
After yet another "breakthrough" infection while taking a daily dose of Augmentin, I bypassed my pediatricians & made an appt to see the ENT....5 days later she had the surgery. He asked about her speech & with this being my 3rd child & each being different, I didn't think much of her not babbling. He told me he could see the fluid & for what she was on & for this long, that shouldn't be...that what she was hearing was akin to the muffled sounds we hear when we take off in an airplane, because of it. When he did the surgery he told me that pus just ran when he made the cut into 1 of her ears & that we did the right thing by not waiting (my pediatricians were/are very conservative in their approach & were content to ride it out during the winter mos). I came home that day & put her in for a nap & she woke up crying when her brothers made a little bit of noise outside her bedroom door. ??? This was new & I thought it was just from the disruption of the day. Then the babbling started....oh my gosh. It was clear she was NOW hearing better. And, she slept all through the night again! The change happened instantaneously & was SO marked after her tube surgery.
The moral of the story is, even as a seasoned mom, the only way I knew it was her ears was for the docs to check them & that I had to take matters into my own hands by being "done" with all the antibiotics & calling the ENT. How I found him was basically tossing a dart at the phone book....I knew he worked out of Children's Hospital here in Pittsburgh, was about it. By the way, 1 set was all she needed & she was MORE than fine afterwards.
Don't you wish each child came with their own handbook that comes out right after the placenta..? ...for problem X, turn to page 32.... :-)
Good luck!
