These long-sleeve Disney Little Einstein pajamas are available for only $4.99 with free shipping. I ordered the “June and Annie” ones for Rosie a few months ago and they are excellent quality. The weight of the fabric is good for her – it’s warm but not as warm as the fleece ones that I also bought her for winter. I think these would also be good for into the spring or longer if you sleep in a cool room.
You order them on ebay, but it is Official Disney – Sold and Shipped by Disney Store. I received mine quickly and with no problems at all.
The “June and Annie” are currently available in Sizes 2T to 5T and the “Leo and Quincy” in Sizes 2T to 4T.
