I'm certain the wisdom of mumsnet will have a good answer for this one, I'm just too sleep deprived to think clearly this week!
What do you put a crawling baby in to go outside? My eldest didn't crawl so this wasn't an issue as I could plonk her on a picnic blanket with a waterproof bottom until she could walk. Do they wear shoes (which I thought was a no-no until they were walking, but then they'll get cold/wet toes!)? Some sort of all over waterproof thingummy? Should I be protecting their hands from cold/wet/mud?
It seems like a stupid conundrum to have, I'm certain there's a really obvious answer, but I don't see any other crawlers at the playground at the moment so don't know what it is!
