Renewing a child’s passport

[calvemjoe]

Help! I need to renew both mine and my child’s passport. I did mine first because there was a shadow on her photo. Logged in the next day to do hers and I need to include my passport number and her fathers to prove she has British citizenship (not sure why, she already holds a British passport). Do I have to wait until my new one arrives or can I do it with the one I’m about to send back 🤷🏼‍♀️

As you've sent yours away it's probably best to wait for your new one to come back. If you'd waited you could have sent them off together with both reference numbers on the envelope.

I have waited so I’ve used it and sent them both together. Thank you for your reply.
