1. Add some document showing your mom has strong tie in China.
2. Think of why your mom will visit Canada during off-tourist season. i.e. being with you two during Christamas season, and coming New Year, or you may want to write another letter for your mom represent to visa officer.
3. If your mom mentioned baby last time, don't mention it again, but be prepared if asked. i.e. you already arrange for a nanny in the neighbourhood, your mom really likes to comfort you, get you prepared for labor, baby nursing etc, but not a long stay.
4. I am aware of several cases successful after trying again.
Good luck.
