Our little one is a bit over 3 mo . Before anyone jumps , our pediatrician gave the go ahead she is about 16 pounds STTN multiple times and rarely requires a feed when she wakes up at night before Ferber , we would take her on us and rock her back to sleep for an hour . We are pretty sure she is OK STTN but we decided that if she would wake up 5 hours after her sleep time so around 1 AM , we would feed her anyway until she is 45 months . So far , she did not wake up the 2 ferber nights . Thanks for helping ! <| sep |> There are numerous praises from 19 th century of the invention of the selfsnuffing wick . Goethe craved for an invention like this , and ot was a regular point of conflict in marriages about whose turn it is to cut the wick .
