haven't a clue Soni I would ask at hospital it may dislodge something I would have thought being so early on. I know its not the same butt my son had 3 lots of gromets and his last lot at age 12, we went on holiday that year we knew he couldn't fly because the pressure could force the gromet out or do more damage to his ears, however we went to Sapin on the bus and to a theme park. When we cam back 2 weeks later went for his check up and the gromet was out we think it was done on the Dragon Kahn roller coaster, as did the doctor. xx
