I bought the larger, warmer version of SwaddleMe when my son who at 2months of age outgrew the small cotton versions. As the weather cools, we have used this fleece swaddle more often. It is warm and so only a onesie or light cotton pajama is all we use underneath it. Seems to work well. Since it hasn't gotten that cold yet, we still use a cotton one rather than the fleece, but are likely to use the fleece more often in the winter--providing he still fits it!
