"That baby is his brother."
Translation:Ce bébé est son frère.
Ça = That as a pronoun. Like I read that = Je lis ça. If you want to use demonstrative, you have to say ce/cet/cette I read that book = Je lis ce livre
I get really mixed up with the French for this and that. I've always thought that ce meant this (or it) and if you wanted to indicate "that" (as in not this one) you used la (with a grave on the "a" but I don't know how to do accents on these pages!) So I typed "ce bebe la est son frere" (with all the accents) to show that it wasn't this baby here close to me, but that baby over there who was his brother. It was marked wrong, and I'm not sure why. Can anyone help?
