DD2 had her first lot at 16 months (June 10) she had then 5 days after appointment because the concern was that if we left it longer she'd get sick again, we took the first available time, was in and out of hospital within a few hours, no pain.
We were lucky her's lasted 18 months before they fell out completely, unfortunately she already had glue ear again and had her second lot in and adenoids out 6 weeks ago, we waited longer this time beause we found out just prior to christmas, she was in recovery much longer due to adenoids, about 4 hours longer.
Both times were private.
