Oh Trish hun,
I agree with what Tanya has said to, perhaps when he has been able to express his fears and concears he will feel lighter and more able to start accepting and loving your new baby,
He must really be feeling scared to be reacting this way, I think some reassurance that you love him and that another baby is not going to 'take' you away from him will help alot.

THinking of you sweety I know in time everything will be ok.

Much love and huge hugs
