My daughters night time routine is no longer

Hi I.M's

I'm having some trouble with my 23 month old daughter. She has always been a great little sleeper at night time, and ever since we have moved into our new home...... 4 months ago she no longer sleeps through the night unless she is in bed with me. It is starting to become a serious issue, i am due to have my second baby in May and i have been trying so hard to get her back into routine but it just isn't working. And I really don't want her in my bed whilst im recovering from giving birth the my second as well as everything else that comes with a new born. Also she has been in a single bed for a year now.

Any tips would be ever so helpful!
