I have read/heard so many stories of children knowing mummy was pregnant before she did. I read one in New Idea (I think) the other day when a little girl/boy said "mummy you have three babies in your tummy- one for daddy, one for you and one for me". This was BEFORE the mother learned that she was even pregnant and expecting triplets. Chn are very perceptive and have terrific psychic abilities that they have no qualms about using. I have no doubt your DS knows full well there is a baby inside when he points at your tummy. Their psychic ability is not strange to them (lie it is to us) , just completely normal. I have heard also that they see the souls of animals...
