what tog sleeping bag for a four yr old?

[Holymoly321]

a lovely friend wants to buy DS a Cars sleeping bag for his birthday. We've just bought a tent. I think it's about a 3 tog - is this going to be warm enough for camping? We be going anytime from spring through to autumn I guess...

anyone?

Maybe it's not warm enough for using in a tent - it can get really cold at night in a tent, even in warm summer. I know it's normally steaming hot in the morning, but that's the effect of the sun - during the night it can be freezing. Try googling the question, or asking in Millets or other camping shop.
