"You're making a rod for your own back", "So, she will scream, so what?" and "You are soft in the head" (on learning we do not leave DD, 11 weeks, to cry in her cot until she falls asleep).
"You need to show that child who's boss" (on observing DS, 3.11, exhibiting normal 3yo behaviour). Ok she may have a point on this latter one but the above comments have really really pissed me off.
