No words other than cuteness!! Friends loved the red plaid baby onesie and will for a few more months …..growth, right!
They are so soft! Bought the matching infinity scarf so when baby is here, we can match :)
LOVE these jammers and my little one will literally pull them out of the dryer and ask to wear them. True to size and I am So happy with this purchase. I will be buying more.
