I love baby wearing! I also love to encourage my family members to wear my daughter. I do this because my daughter loves to be worn in a carrier and I want her to feel comfortable being worn by other people besides myself. I also feel like it strengthens the bond between her and that family member.
Sure, someone can just hold her or put her in a stroller, but that's not the same thing. She can't hear your heartbeat or feel your breath from a stroller. And I have to say, arms get tired after a while!
My little brother is 17 and I encouraged him to wear my daughter in her Tula. He is always amazed at how calm and quiet she is when I wear her. He told me that he will have to remember all of the things I'm doing for when he has kids. I just love that he can see the benefits of babywearing and will pass that on.
My husband and my 14 year old son wear her on a regular basis and they both enjoy it. It warms my heart to be passing on something that is good for both baby and family!
