Hi H.!
I say go for it! My son was just six when he had his tonsils and adenoids removed. Due to the size of his, they were causing a lot of health problems (consistent/persistant coughs; lack of sleep for all in the family; he ended up with sleep apnea; snoring; everything he ate was "too crunchy" and we couldn't understand why??).
Needless to say, after many peditrician and cardiologist (my son had open heart surgery at one week old - so they were fearful that the coughing was the start of congestive heart failure) appointments, our cardiologiest told us to see a pulminolgist. When we went to see him, he said who did your tube surgery (ENT); go see her, his tonsils are "impressive." Our ped also never thought they were an issue - too large. We went to see our ENT and guess what... that was the culprit!!
After surgery the ENT came out and said to me, are you sure he has never choked on food before...I said no; and she said, wow, with as large as they were upon examination, I could not believe how large they were when I got them out.
It was three weeks of sheer recovery h-e-@# but well worth it after it was overwith (and I am told that the older they are the shorter the recovery because they are more apt to eat the popciles, drink, etc.)!! His sleep apena was gone (I could hear it through the monitor as he sleeps upstairs!!), he no longer snored, his eating was unbelieveable!!! And his health improved wonderfully! He no longer had dark circles under his eyes!!
We had it done on Dec. 14th and when he went back to school after the holiday break, he ate school lunch from that point forward...food was no longer "crunchy" anymore; the first half of the year we were packing a cold lunch due to that crunchy food. We came to realize that the food was not crunchy, his tonsils were just that large!!
Exactly one week shy of a year we went to his cardiologist appointment and he had gained 4.5 pounds and grown 3.75 inches!!! This is huge since he is only a 43-lb 7-year old today!
Here is my tip for your daughter...make sure she drinks and drinks and drinks...that will certainly help her!!
Good luck!! If I can answer any other questions, please feel free to contact me!!
