I can't believe what a bunch of WeeWillyWinkie busybodies you all are!
Its a very British thing that children should all be in early - lots of people let ther children have long naps during the day and keep them up in the evening. I think its nice really, as it means they probably see more of their Daddies.
And as for being in the jarmies...well? It little kids for crying out loud! I don't think it matters a skerrick tbh, and if I see kiddies in their jarmies at the shops I think 'oh bless'.
As for getting them dressed at the pool, I do things like that sometimes - take the jarmies to change them into, or feed them a sandwich in the car instead of 'breakfast'. For me and my kids, faffing around at home takes sooooo much longer that doing it when out. Breakfast takes an hour, a sandwich in the car takes 2 minutes. Getting into jarmies in the carpark before coming home takes 5 minutes, getting dressed once at home takes 30 minutes.
I have friends whose children don't own jarmies though. They just put their kids into their clean clothes at night, and they sleep in them and wear them the next day! Bingo! Perhaps thats the answer!
