I was BFing Charlotte and she fell asleep eventually, as usual. I had her in a football hold tilted towards me. I readjusted her position and just so happened to catch a glimpse of her arm she was laying on... it was almost blue!!

I panicked and picked her up. The onsie she was wearing had no sleeves and the arm holes had no elasticity to them at all and her circulation was cut off at her shoulder.
She's fine, but I couldn't believe it! Why would they even manufacture something like that? That really could have ended badly. It was the first time she ever wore that onsie, so obviously it happened pretty easily if it only took her wearing it one time. I threw it away and I will certainly be checking the rest of her clothes for the same problem.
I just wanted to share. Maybe I should have known better or maybe it is the first time mommy in me, but obviously I never thought to check for elasticity in arm/leg/neck holes in her clothing. It is amazing what can turn dangerous for her. I am not looking forward to baby proofing.
