The exact thing happened to me, except my son's first surgery was at 10 months and his second was at 18 months. After the first surgery he did so well for about 2 months, then he got pnemonia and things got bad again because he had so much fluid from his nose trying to drain out his ears, the tubes got blocked. I was so scared, I did not want him to have to go through a second surgery. I went to his pediatrician to make sure he agreed with the second surgery (he did), then I found a second ENT that over the phone was like, I don't like doing a second surgery this young, it may not be necessary, come in and bring his chart from the first ENT. He said that yes, he definately needed the second surgery and that the risks are minimal, though always scary. My son had to be intubated during the second, when they also removed his adnoids, it was so scary for me. By two days later, he was so much better and now about 4-5 months later, his speech is so much better. He hasn't had an ear infection since, and when he gets colds they don't drain out his ears anymore (I think the adnoid removal helpsed that the most). Also, our ENT said he's adnoids weren't enlarged when seh removed them, but now we're glad she still took them out because most likely they were causing problems. My best advice is, if you really worry it's not necessary ask your pediatrician and, if you still want seek a second opinion, but sometimes it can be the best help! Feel free to comminicate back with me if you have any further questions or whatever and best of luck to you and your son!
