I have three kids. Two have tubes. and both got them about the same age as your two boys. And I waited too long on the oldest to have her tubes inserted. She has an unrelated speech disorder and it would have been to her advantage to have had tubes earlier. She is nine and on her third set.
While there are risks to any medical procedure - and we've had several - including the ABR at Children' down town - tubes are typically pretty simple.
With just tubes, the anethesia is easier - no intubation typically - just a liquid to put them to sleep.
I remember being there when they woke up post-op and being able to hold and rock them. And they were little grumps - but allowed me to sooth them.
You will get instructions - like bring a sippy cup or bottle for them. I don't ever remember any serious bleeding after just tubes.
And Make sure you have someone go with you! So each little one will have a big one to love on them. And so the other person can drive and you can sit in the back with them on the way home.
And just plan a quiet day for all when you get home. Movies and naps. I stock up on popcycles, chkn noodle soup and other soft comfort foods that are easy on the tummy.
One other thing - Make DARN sure that before the procedure you have clear care instructions (that you understand) and contact information on how to contact the DR after you get home if there is a problem. I have had two ENTs. One gave me her cell phone number after a procedure to contact her (we had more than tubes that go 'round) and the other I could never get past the nurse when I had questions. One time, I finally got a "take her to the ER" after three hours of begging for some direction via phone. If you are not going to have access to the doc afterwards for emergency questions (not the simple ones a nurse can handle) then I'd think twice about my doc.
I am not trying to scare you - there is LITTLE to be worried about here - but I have been through this SEVERAL times + tonsils + adnoids + sinus surgery... You get the idea. It is MUCH better to be prepared than out there on your own with no one to contact...
Good luck - You (and you boys) will be so glad you did this. The upside is almost NO ear infections afterwards AND when they do occur - all you need are drops. No oral antibiotics.
PM me if you have any further questions.
my best -
