night tremors in 2.5 yr old (im pregnant with #2)

wondering if anyone ever went through something like this while being preggo with #2 or #3.... DD is 2.5 , co sleeps with us, she sleeps fine etc. etc. shes excited abotu baby sister.... for the past week she has been waking up at night (sometimes 2x) crying hysterically, to the point where she is shaking, crying saying mommy hold me, mommy i love you; holding my face, now the first 2 or 3 nights i thought it was night tremors or whatever so i picked her up and held her until she fell asleep (2 minutes and i would put her down ) & everything was ok. Now she just wants to be held by me, while im sitting, mind you im 29 weeks preggo and sitting upright is not the most comfortable thing in the world. last night she woke up and i refused to pick her up and hold her bc the other 3nights we were both crying bc i couldnt take it anymore. i was sitting for 30 minutes with her in my lap and i was so helpless.
so last night my hubby took her and she was just crying for me; and asking for me, i try to ask her; are you dreaming about something? is everything ok? i am here i am not leaving, i love you, i will lay down with you etc etc. so she finally fell asleep with me in her arms, and she was touching my face - So ofcourse i have no idea what is happenign.... I am thinking that it could be anxiety about baby coming home soon? What else can it be?

So sorry that must be so hard for you to see her so upset. I'm pretty sure that in night terrors the child does not actually wake up or is in more of a sleepwalk type state and has no memory of the incident. It sounds like your DD is awake and just very upset. That being said it would make sense for a child of your daughters age to have nightmares or fears about the upcoming changes and to be nervous about how that will effect your relationship with her. So I'm sure that's what's happening. I would make sure to give her some extra attention and reassurance. Before being a SAHM I was a child therapist(social worker) so I would say this a totally normal reaction for your daughter. As a mom of 2(soon to be 3) with my oldest DD being very jealous of my 2nd and her having a lot of nightmares with sleepwalking,etc I give you extra hugs. I'm sure you don't need any extra guilt right now. It's so hard to see your child suffer, but it will get better:)
I would try to lay next to your DD during these episodes if you can't hold her and don't blame it on the baby that you can't hold her(say your back hurts or something but not why).
I would try to ask her about it the next day in a casual conversation rather than when it's happening. I know my DD has no clue what's going on after a nightmare but can sometimes talk about it the next day. Good Luck!
