Maybe edit the original post to make it clearer? I personally would have no problem if my sister gave me a call like that.
I agree with pps that we shouldn't wake a sleeping baby. Unfortunately i had to wake DS up every 2 hours to feed because i had GD, he kept waking up every 2 hours for 4 months until we went to sleep school. He still wakes several time a night, eats very little and a bit behind on rolling/crawling.. but i have no problem with my friends brag about their bubs on fb, i'm happy for them and sometimes ask them for advice.
