Thank for your suggestions! I really appreciate it! Jacob would never take a pacifer, we tried many times. He also had a hard time with a bottle because I had to pump some milk for him when he was really little and had to be left with my husband. I guess he just always prefered me. I will try to let him hold the baby more and put the baby on his lap too while the baby nurses. That might really help. Jacob does kiss Caleb a lot. :)
