In my family we have our own sizing for baby clothes. On my side we have big babies so we have our own sizing for baby clothes. I was wondering if any of you 2+moms have your own sizing that you go by and if any of the ftm have been going on their own intuitions or by the size on the clothes. I went shopping with a friend who just found out she is expecting and was explaining this to her because I called my mom to recap what size we had decided my baby would be in around Christmas time (gotta love the winter clearance). My friend was thinking baby would be in 3-6months but because I know from being around babies my entire life that was not the case. So, how who has their own sizing they follow and what do you follow by?
