I read a few different books and then chose the one that I was most comfortable with albeit with a few minor alterations as needed for my kiddo . I used Healthy Sleep , Happy Baby , but all sleep options work for someone , so I would suggest finding one that you read and makes you think that makes sense . Happiest Baby on the Block was also a crowd pleaser among my momfriends . As for house temperature , we did 68 degrees as suggested by our pediatrician . If baby seems to get cold easily my second did , I would make sure to use layers while dressing for bedtime . Mine needed a long sleeve onesie , warm footy pj , and a sleepsack through winter . <| sep |> I ' ve got one I ' ll sell to you if your EU based . <| sep |> I don ' t know your version .
