Ahhhh...welcome to motherhood.....for some reason, people seem to think that "their" ways are the best when it comes to raising a first child. Everyone has their own experiences and ideas on "what is best" and people are oh so willing to verbalize those things...LOL
Rain....you do what is comfy for you, what feels right for you and Jeremy. As with every first time mom (and subsequent children too) you will learn along the way. You are very in tune with your son and his needs and your own needs as well.
You are doing a great job......and as difficult as it can be to hear from your aunt....I'll bet she said it with the best of intentions. So sorry it got to you though....sometimes folks just don't know when to back off ... especially when there is no harm being done
I always try to remember that there is more than one good way to handle any situation.... but what works best for you is perfect!
