When I first started practicing, I was surprised by how often parents asked me what temperature the baby’s room should be. Now, after years, I have finally come up with a concise answer: The perfect temperature for Lucy’s room is room temperature. Not too warm, not too cold. In other words, whatever works for you works for her. At night, if you do want to make things a bit warmer, I recommend one of those sleeveless sleeping bags, especially for young babies, as there’s no risk that it will cover up the head.
As for outside temperatures, you can take Lucy out in frigid winter temperatures. unlike older kids, babies are easy to keep tightly bundled up. On the other side of the spectrum, heat is also fine; remember, for nine month Lucy lived in a kind of terrarium, with a minimum temperature of 97 degrees, without any air conditioning.
