My baby has yet to be touched thanks to this magical sign. Many people walk by with the urge to pick up, touch, or even kiss my baby, and they’re at bay. I would recommend this sign for beginners all the way to experts. This stops the “baby holders” as they’re called. It has even deterred me at some points. Please keep in mind this isn’t supposed to be ingested, it’s fun to play with and not to eat. My only problem with the sign is that it doesn’t come with an attached squirt bottle or an air horn.

Lion Silicone Bib with Crumb Catcher

I have tried waterproof bib and IKXA bib, and I love this one the most. The pocket of this bib really sticks out well, it catches the food perfectly. The other normal flat plastic bibs I have cannot catch the drops even they contain the front pocket. It is so easy to wash, I only rinse and air-dry it after use. I do have a normal plastic bib got the fungus growth all over the adhesive loop. But I don’t need to worry about that situation happened to this bib, because it made from food grade silicone.

I fell in love with this beautiful print when I saw it. My girl was 6 lbs 3 oz at birth and most of her gowns fall off of her shoulders but this fits perfectly and it’s so soft!

Leopard Print Labor & Delivery Nursing Hospital Gown
$35.00

I choose this gown, solely due to the leopard print which I'm crazy about!!! I was worried about sizing because this is the biggest I've ever been pregnant for reference I'm 36wks & weigh 186lbs. Before I was pregnant I weighed 140 & a size 6, I'm also tall 5'9! I'm telling y'all PURCHASE BASED ON YOUR PRE- PREGNANCY WEIGHT! I was going to order the medium-large but I'm so glad I didn't it woulda been wayyy too big! The small-medium fits just right & I have room! This gown is ahmazing the fabric is soft & stretchy! Definitely buy it! I'll be using this well after I deliver too!
