A friends 5 year old recently had his out as well as adenoids and grommets replaced, he was misrable for a week and off kinder for week, they then went away 10 days after OP (trip was booked 6 months before they knew he needed them out).

By 10 days he was much happier and perkear ad eating as normal again.

In the first week she kept up the painstop and tryed to keep him doing quiet activities.

Hope your little one has an easy recovery.
