Update 5/27/18
I have had these for just about 2 weeks now and have rotated them with the other 2 and a pair of burts bees - I am so disappointed - after maybe 4 wash and wears these look like a used pair of pajamas from a thrift store - they have not only completely shrunk making my son curl his toes in the foot area but they have pilled horribly
You are better off investing in something else

These are very cute pajamas and the cotton is very soft, I bought the largest size offered 6-9m for my 4 month old who is 26 inches long. I washed they first and being all cotton they definitely shrunk - but I was able to stretch them back out, however the foot area is too small and a little tight.
Another feature I am happy about is the finish seams all around and the edging on the sleeves that is reinforced.
I would have given 5 stars but the shrinkage was dissapointing especially since the size selection was limited.
