i know ths is going to sound a little weird to alot of people..but i was the same age as you when my second child was born..i also had a mommas not like there was no tomorrow..i too was worried how i was going to help brandon (my first) make the transition from the only child to a big brother..then one day his dr. told me i should get him a doll...i laughed and told him he was crazy!! well i got him the doll..and for a few months before the new baby came brandon and i would practice with the doll. we would do things such as feeding, changing, burping, and putting him to sleep..(to my surprise my macho boy loved it)well when the baby came..and it came time for mommie to feed or change the baby..brandon would get his doll and do everything i would do to the doll.(once he even got on to me b/c i was being too loud and i was disturbing "his baby")lol and to show him that he was being such a big brother i would allow him to participate in the feeding and changing of the new baby..then as the baby got older he got to hold her more often,etc..i can honestly say that b/c of that doll brandon never showed any jealousy or resentment towards the new baby.. i have since had 3 other children and have done the same thing with all of them..and never had any probles with the transition.. hope this may help you..congrats on the new baby and good luck
