I have six kids and the same thing happened with almost all of mine, it will get better and all I can say is keep trying. I use to have my girls get "their" babies pretend to the a Mommy with me....to the point of feeding them when I was feeding the baby....washing the doll when I washed the baby...it takes a little bit more time but it helped out. I would tell them what a good Mommy there were. I would asked them to be a part of the baby and help me with things I need with the baby....sometime just knowing they are still important is a hard thing to telling them but showing them is sometimes earier. It takes a little bit longer but eventually teh 5 year will come around. :)
