Hit hard still taking another step forward.

I have read an article on validation. Feels a bit condescending.

I messaged W to ask how S3 was this morning (suffering from constipation) and had a go at validation. Couldn't see many places to use tbh:
08:34, 16 May - T1000: Any sign of S3 picking up?
08:36, 16 May - W: He has done the toilet
08:36, 16 May - T1000: Good! Is he better for it?
08:37, 16 May - W: Think so. He went in the night
08:37, 16 May - T1000: Last night?
08:38, 16 May - W: Yes
08:38, 16 May - T1000: Ok thanks
08:39, 16 May - T1000: Hows S1 been, keeping you up still?
08:41, 16 May - W: He is full of beans. Still wakes up twice. Had a few tantrums yesterday. Wee sh1t
08:46, 16 May - T1000: Thats not good.
He can be wee sh1t can't he.

Can any validation masters point me in the right direction?
Is there times where there is no room for validation or there is no need for it? Or should I validate 24/7?
