I'm super wary about giving Zack anything but breastmilk. I want his gut to develop in the best way possible, and there are no studies I could find on how vit. d supplements affect the gut. This article made sense to me, and I have been supplementing myself and get outside time (and Zack gets some now, too) so I'm not worried about it. http://www.007b.com/vitamin-d-breast-milk.php
I've been thinking along the same lines. DF is really big on protecting the girls from the sun. But when we camp out under the trees on the weekends, we let the girls hang out naked in the diffused sunlight for a bit. Added bonus, they love it! All smiles while they wriggle on their blankets.
Went up to Sedona for an extended weekend to work on wedding plans for October. We did a tasting with the caterer and took the babies with us. Fiance was really nervous about them coming along. But they slept the whole 2 hours in the restaurant while we chatted and stuffed ourselves with deliciousness. I love babywearing. I don't think they would have slept that well in their carseats.
