I'm looking for recommendations on baby bottles that dont leak.

I use the playtex vent aire right now and they leak too much. My daughter is 21 months now, and I give her a bottle when she goes to bed, but I just give it to her and she puts herself to sleep with it. They leak so I have to wash her sheets every second day. I have no intentions on taking the bottle away from her as she refuses to drink milk in the day time. So I'd rather just give it to her in the bottle at night.
