...mums that disguise a brag about their baby in the firm of an annoyance...for example "(sigh...rolls eyes...) I can't believe blah blah is crawling/walking at only x months ...urgh....s/he just on't sit still (cue eye roll)!"
Why don't they just say "oh guess what blah blah just crawled/walked!" I ind this fake annoyance thing a very odd way to brag(!)
