When did your DC#2 start STTN? I am extremely exhausted with DS. I think we were really spoiled with DD who started STTN at 8 weeks. I find myself getting impatient with this with DS at times, but everyone tells me that I am expecting too much from him.
Also, did you do any kind of sleep training with your little ones?
It's amazing how these kids already are sooooo different from each other!
