Please tell me this is normal??

I am 29 weeks pregnant with a baby boy and already have a baby boy who just turned 1 last month. I absolutely love my son and I am excited for this baby as well, Im just feeling a little overwhelmed. This baby was a bit of a surprise, I was on birth control and everything, but I guess he was ment to be. Im just wondering how I am going to be able to handle a new born and a 1 year old. My son has been walking since he was 9months old and now he is into climbing and scaring me half to death..lol and he is extreamly! attatched to me and gets jealous of even my husband when he gives me a kiss. Please tell me these feelings are normal and what I can do to try and get my son to possibly not be so jealous. I also cannot get him to sleep in his own bed, any idea's? I have already gotten him off the bottle and I am working on the pacifier (which is the hardest), now I just need to get him to sleep alone. Help and some advice would be appreciated! Thanks!
