Renee, Jack's a little younger than your dd but every now and then he'll go through a stage of waking in the night and only going back to sleep in our bed. I don't think it's jealousy. I am not sure if it's nightmares, or just adjusting to something new in his life, but it never lasts long. I hope this is the case for you too and it's just a phase. Some people might disagree but I think spending time with them and making them comfortable will solve the problem more quickly than leaving them upset, so you sound like you are doing everything right. GL!
