Stace, I would not cancel if I were you. You need the time to yourself, esp. if you're a SAHM!
It's not as though you're leaving him with a complete stranger! Auntie will be able to entertain him. My DS cries every time I leave him either with his Marmie (my mother, who he adores) or his Day Care providers, who he also adores!) He even cries when I leave him with DH! Usually 5 minutes later, he's engaged in something else and has completely forgotten all about me.
Re: sickness, sleeping and SA...
Past few nights have not been so great, he was feeling poorly and not sleeping well. He slept in bed with me on Monday night because he was feeling so badly! He tossed and turned like crazy, but actually, I think it was a good thing because I realized that he was propping himself up in order to sleep. Which makes sense with the double ear infection we just found out that he has!
So, last night I gave him some Calms Forte for kids (homeopathic) to help him relax, some tylenol for the pain, and his antibiotic...(quite the cocktail!) and a pillow in his bed to prop himself up. He woke coughing a couple of times, but got himself back to sleep each time without me even going to his room! No crying either....So hopefully we're on the mend.
I also took the air bed out of the nursery, I think that he was looking at it and then wanting me to come in, and then when I was there, he wanted me to hold him! Maybe an out of sight out of mind thing, I hope!
Keep up the work with the PD method, I found it worked very well for us.
