Moms pregnant with #2 + how is your older child coping ?

I feel like my DD (4.5yo) has been so difficult lately and I think the pregnancy has a lot to do with it . She has always been a "good kid" but she has changed so much this past few months , she has been acting out a lot, has become so clingy, cranky,whiny. We try to be patient with her, but it's becoming hard. I wouldn't say she is out of control, but she challenges us constantly, pushing our buttons.
Just wondering if anyone is going through this or has gone through this and what worked to make it easy on your older child and for you .
Thanks

DS is almost 3.5. He's really excited to be a big brother and talks about the baby a lot. However, he has been super clingy since we told him about the baby. He always wants me to carry him and gets upset if I don't at least pick him up for a little bit. Recently, he has been speaking in a baby voice at times. I don't have any real advice, but you're not alone.
