Urgent: is it ok?

Is it ok of I put DS1 (19mths) and DD (3yrs) in DS's cot together to sleep tonight?

DD had an accident and I don't have spare sheets etc. and she's in our bed but DS2 and I don't fit in with her in there (double bed) as she sleeps taking up as much room as possible!

And by ok I mean safe

mine cosleep by choice and they are 18 months and 3.5 :)

I'm planning on putting my two together in a double bed at that age :) Hope you all got a good nights rest.

Thanks :)

I tried to put her in his cot but she woke screaming "I don't want to sleep in the cot" anyway she came up with a good idea and said she wanted to sleep on her little flip out kids chair thingy. And slept on the floor in our room. When DS woke he thought it was so cool he went and grabbed his and put it beside her.

After all that didn't get much sleep!
