Hello Loops Galore, I hesitate commenting on anyone else's shop, when mine needs work , lol
I would suggest doing a store banner, the pic for the banner is not very high from top to bottom so it's a little tricky,
You could lay out a couple of your items on a solid color background with maybe some fake flowers in the corner, just an idea.
I have been trying to make my pics better, still a work in progress, I bought some poster board to use for a background for my pics,
you can buy a couple different colors, to compliment the color of the item. You might try getting a life like doll to model the baby items.
Having a online shop is always a work in progress, Happy Crafting
