It can be tricky dressing a newborn because onesies have to be pulled over their heads and trying to squeeze their arms up and through the body is not easy.  When my daughter was less than 3 months old, I found that these one-piece kimono style bodysuits were perfect.  And, the built-in hand cuffs are so nice too because the little mitts never stayed on my daughters hands.

This is the perfect clothing item for a new baby!  The only drawback to this one is that it's expensive.  But, it's hard to find long-sleve kimono style badysuits, so that's why I bought it.
