Little visitor

My sister asked us to watch one of her kids last night (overnight) so she and her hubby could go to a work Christmas party. At first I was a little upset because we did have plans for today and it seemed like she wasn't willing to make any concessions regarding pick up time. Anyhow I said if you can pick up the kid so we can get to our function on time then bring the kid over.
My sister and family was placed with a new foster baby this week. I inquired about where the baby would be going and ended up offering to look after baby too. Truthfully I was a bit nervous about having a newborn in the house under my care....it's been four years you know! I was also a little anxious about how having this little one in the house might alter my desire to ttc and try to add to our family. Anyhow this baby is quite sweet, a little girl born Oct 5 (ironic that she was born at the time my march m/c should have been arriving) still a tiny newborn really.
Our evening went ok but I admit I had thoughts of do we really want to go back and start all over again with a new baby. The fussiness, the not knowing what's bothering baby, all those mommy worries, the middle of the night feedings. Baby girl was a bit fussy I figured out that 4 oz is just not enough for a feed anymore. She was barely lasting two hours. So easy fix....feed hungry baby... She slept well overnight and was up twice to eat.
By the morning I had had enough snuggle time to feel comfortable, and a bit bonded to this little one...the desire is still there. Even with all the anxiousness and sleepless nights the desire is still there. B was excited to have little one in the house and called her his little sister....so sweet :).
I see Dr M next week.....finally time to get the ivf ball rolling (I hope).
