Need some input.

My little princess is bout 18 months and we've been working with her on sleep training, she kinda gets it but still has some issues with it. But I've been going at her pace. But my husband and mother in law have been pushing for her to really get it down. But I get almost bitched at bc she will play and then come up to me and fall asleep on me. I get we're trying to get her to sleep on her own but I feel like I'm not doing anything as wrong. She feels comfortable with me. Am I wrong or do they need to lay off a little?
