I have had a few of the nasty attacks and they are mighty unpleasant. More often I get the tightening/ache of an attack building up. As soon as I feel the first twinges, I whip off my bra. Then I eat a couple of those Buscopan (aka Gastro-sooth) and if that doesn't settle it then I jump in the shower. The shower helps during an attack too - I have it as hot as I can stand it.

Don't stress about the childcare etc too much for now - you will work something out, even if DF has to put the cot right next to his side of the bed or whatever. They will survive.
