Unfortunately it could be that your little one is either reactig the the change of different environment or he just doesn't like it. Take your time to make whatever decision you see fit. I can tell you that my little boy, age 2, does act a little more whiny and needy when dad goes out of town. I noticed the pattern but it took a few trips for me to see it. Sometimes that could be it. But again, do what you feel is best for you and your child.
My son just started a new day care home today. It is with his same provider he is used to, but now she is doing it with her sister in the sisters hoome. It is really nice. However, this morning, my son wanted me to go with him everywhere. It's a new place and dad left to go out of town this morning so we'll see how he is.
By the way, the daycare still has a couple of spots available. If you are interested in stopping by or checking it out, let me know and I can get you the information. ____@____.com
As a side note....I LOVE our provider..both of them now. I would trust her to keep my son overnight before I would trust some of my family if that tells you anything.
