The mommy to be I gifted this too, fell in love with it🩷
Daughter loves them
These bibs are adorable and absorbent! Plus they are so soft, easy to put on, and fit great. We use them daily to help prevent multiple outfit changes so I really appreciate the color options.
This froggie has an awesome crinkle! Baby lights up when he hears it. The frog teether is a little heavy though making it a bit difficult for smaller hands to hold on their own.
Super cute and super soft. Baby loves the little sensory poppers.

Im loving this material. Its one of the softest I’ve found bc some are a bit stiff. I am using these with my Anzy Moses XL Bassinet and they are the perfect size.
Adorable, great quality and exactly as photo’d
