We just received the 3-in-1 as a gift, but my husband is a little wary of using the bassinet feature. I was planning to put the baby in its crib for naps, but in the bassinet next to our bed at night during the first few weeks. Is this safe? I assume it is because why else would there be a bassinet feature, and I can't find anything to suggest that it isn't. Does anyone know for sure?
