Animals and/or Noah's Ark. Alphabet. Books (themed - not as in everyone brings books as their gift). Space. Airplanes (or also just things that move, so trucks, cars, trains, etc.). Or you can just do blues and greens.
My sister threw me and our baby boy a shower this past weekend and did an owl theme. She ordered decorations off of etsy (invites, banner, food labels, water labels, welcome sign for door, cupcake toppers all in owl theme).
Re: shower themes for a baby Boy!
I love the Alphabet and Books idea! thank you!
Little monsters? I see bright, fun colors. Cute fuzzy monsters. Simple patterns (polka dots and stripes).
If we have a boy we are doing this as well! I am glad my fiance settled for a safari themed nursery instead of the baby name Safari lol.
