Announcement ideas???

Cheyenne

I have 1 bonus son and 2 boys and i want them to be apart of the announcement along with my husband. I really want to do sunflower pictures since i adore sunflowers. Only problem is the week the sunflowers are predicted to bloom isnt our weekend with my bonus son. My mom(the only one who knows im pregnant so far) said not to worry if he cant be in it and to do it anyways since everytime i try to plan something around our weekend his mom ruins it and wont let us have him(hes 5). But i dont want him to feel left out later in life looking back at pictures. But sunflowers are so temporary and if i wait for his weekend they may not be bloomed anymore
