I saw this jumpsuit and just loved it, so I ordered it for my son who is just 6 mos old. I did order the 12 mo size, so he would have some room to grow into it for the holidays.  Unfortunately, it runs very small and the 12 mo size is really more like a 6 mo size. It barely fit my son who is 50% for both height and weight.  Unless you have a smaller than average baby, you may be disappointed like I was. The quality is nice - I just wish they had it for 18 mo olds - I had to return mine :(
