I’m a basic child renewal. As long as its straight forward and the picture is perfect recommend to be from a photo booth at the supermarkets should be fine. If you take it yourself or the post office there could be shadows behind the ears highly recommend the photo booths. Then should go down the digital route. With the dates of your travel i don’t think you have to much to worry about. My application went in on the 2nd of march being printed now. Fly on the 7th April. It is very stressful when u have holidays booked.
