I have a thing about natural fibres, especially for the kids and especially for nightwear. It turns out for us that this is a good instinct, because Isabelle gets awful, itchy rashes when she overheats at night. It only took us a whole winter to figure out that fleece footed pjs weren't good for her - we're a little slow on the uptake sometimes (I suspected shrimp).
I used to love a company called Hanna Andersson - still do for lots of things. Their playdresses are a staple around here. But since they were bought out a couple years ago, they've changed the fit on their famous "zippers" and long johns so that they're tighter than a wet suit on a whale.
Yes, before you start emailing me, I know it's a safety standard designed to protect kids from catching fire near open flames. I also know that instead of wrestling my little ones into skin tight cotton pjs, I could instead buy pjs made of polyester (but see above) or buy cotton ones coated in toxic chemicals many of which are known carcinogens.
So you can see why Isabelle is wearing pjs that are so small we had to cut the feet off and Tom prances around in his sister's pink nighties and old-style 'zippers' (in addition to his dad-inherited dandiness). My mom has also been called into duty to sew some pjs, but other than nightie, each one is a lot of work.
My dad came over today with 100% cotton pjs, not treated and I couldn't figure it out. They were called "loungewear" and were European brands (Petit Lem)! ah-ha! So that's the secret - I'm stocking up before the pj police figure it out!
