quick question about pictures lol my son will be 3 in September, and my daughter will be 1 in october (9 days later lol).... I obviously want to get Emorys pictures done, but should I also get Eastons pictures done? my sister in law took some of Easton around his 2nd birthday last year and took is 1 year pictures, but her camera is broken so I would have to go to a studio to have them done (the lady who took their easter pictures does birthday pictures, even provides a smash cake for the 1 year old, am going to look into prices)... I just don't want to seem weird having 3 year pictures done, if it's not something that is not normally done lol
