Clingy baby after sickness.

Thursday night into Friday morning my 9 month old started throwing up. She was throwing up

Stomach bile since she had nothing in her tummy. I ended up putting her in bed with me so I could make sure she didn’t choke and could get to her quicker when she threw up. Friday I stayed home with her and took her to the doctor. All Friday night she wouldn’t sleep unless I held her. Now she has a separation issue. If she can’t see me or hears my voice and doesn’t know where I am she will scream and cry until I go get her. She is struggling to be away from me even if I’m just in the other room. She won’t sleep without me, and she always has slept in her own bed. Is the a normal thing after being sick? What can I do to stop this? I’m due again in two months and she needs to be back in her bed and on her schedule.
