Mine has just said this beauty - [with reference to 8month old dd who had woken from nap and was grizzling, clearly not going to go back to sleep] "Why don't you just leave her until she's screaming her head off?" !!! I thought that was a real corker and had to share that with you all!!!
She had in fact pooed herself and got stuck in a crazy position in her cot so on reflection I'm glad I didn't follow mil's advice.
