you don't have to believe someone created you - but what a wonderful thing to think someone loved you enough to create you - instead of just plopping into your spot in the world. Oh and don't feel you're "doing something wrong" because you don't believe in the wonderfulness of Creation, you're loved anyway - and accepted just as you are. You might be missing something really good though.
I definitely agree with you that moms on this forum are trying as hard as they can to meet the needs of their babies, I'm a mom who did the same and am now coming alongside my 2 daughters and 2 daughters-in-law as they are becoming moms, and also remembering the experiences/joys and wanted to join in the conversation with all of you too!
I do think when we go with the natural inclinations of our little ones it does encourage independence in their development instead of holding them back or trying to stop them from doing what's natural to do something we want instead. I have included a post with links to data, only it was "held" because I am a new member - guess you'll have to wait to see if it gets posted.
I appreciate your boldness in offering advice to the mom asking about swaddling her 5 month old - that's exactly what I was doing as well - just another perspective. Hopefully with all of us joining the conversation everyone learns something new and gets encouraged too!
