I'll be watching this thread because I have an 18mth old and am almost 13 wks pregnant so I have the same questions!

DS relies on me so much sleep-wise (although I think we['re in the middle of a major 18mth sleep regression!) and we're the same as your other examples. I guess I just figure little people DO change at 2, they understand so much and we can talk and explain and reassure so much more than what we can now. I think also making DS a part of things as much as possible will help.

...I hope...!!
