My 5yo ds had an adenotonsillectomy on Tuesday. He reacted badly to the anaesthetic (sick, alternating between lethargy and hysteria, couldn't eat or drink) so was on a drip for 24 hours afterwards. He's now home and is eating and drinking ok and no longer snores but his voice has gone really strange. Really high-pitched and squeaky and girly sounding. Is this normal? Will he go back to having a 'boy' voice at some point or have we broken him? I'm worried that he'll go back to school after summer and everyone will laugh at him.
