Before you teach your kids the valuable lesson of "if you don't have something nice to say, don't say anything at all," you might to have to endure some fellow mamas who totally missed that lesson. While these ladies aren't necessarily trying to be outwardly mean, they have a tendency to use their words as daggers with "innocent" statements. From highlighting how easy it was to breastfeed to letting everyone know how well-rested they feel because their child is sleeping through the night, these women hit other moms right where it hurts with their "wonderful" news. Unless you want to make other moms cringe on the inside, be happy for your own fortune while avoiding these nine humblebrags.
