Need solid and accurate answers please
We are planning to go abroad but child British passport expires in 5 months time from the day of travel day. So my queries are below
1) Can my child travel abroad and come back to the UK without any issues as his British passport validity left 5 months only. or any risk?
2) what would happen if we planned to go with this validity. Do they stop at British airports or abroad airports as well?
3) If I apply child British passport renewal NOW then how long it takes to come back to receive new passport?
4) Please send me the correct link now to apply Child British passport RENEWAL?
5) What documents do I require to apply this renewal?
6) any fast track to apply this?
7) what is the fees ?

Please send me details as soon as possible as I need to apply renewal in 1 or 2 days as I don't have enough time
Thanks experts
