I loathe these comments....ive had them....with all 4 of mine. They look at you with sad eyes and ask 'is he sleeping thru yet?'. 'No, im up at least 3 times a night'. "ohhh cheeky bugger, dont worry, it will soon pass".....he needs me, hes not cheeky, hes exercising his survival !!!!
I will never forget being laughed at by a work colleague when i said i have to get home to feed my baby (DD#2 - 13 months old). He said 'but shes eating food, steak, potatoes, why does she need your milk ?'. He looked at me like i was a freak. Idiot.
Like you said...some people really, really need to just mind their own business and shut up !!!
