For the smallest children, I advise them to bring a toy that they like, as it helps with interaction and makes them more comfortable. Preferably it is not a very big toy that can cover the child's face and that it is something that the parents don't mind being in the photograph. Bring water and snacks.
Children will behave like children. Possibly they will not always be cooperative and parents need to relax about it. If necessary, take a break! Parents often forget about themselves to be extremely focused on the child (if they look at the camera, if they laugh, if they don't have their hand in their mouth, etc.), avoid this, as they believe that the photographs will be fine.
I do not send unedited photographs.
Making a photo starts before the moment you press the button and ends with the editing of each photo, involving a lot of dedication, work, care and time! Therefore, I appeal to your sensitivity when it comes to image manipulation. Changing the images, whether in terms of cut or color, jeopardizes work, art and respect for the photographer.
Yes, I work alone.
When it makes sense, that is, when it involves an event or when it is necessary to make a more complete photographic record, with a larger coverage, I work together with another photographer and friend, so that the final result meets what we intend and the that you idealized.
