I don't believe in CIO. And you yourself said that you and your husband are more into attachment parenting. If you truly believe the emotional, physical, and psychological effects of CIO vs attachment parenting, then I think you have your answer.
At 10 months, she's probably developing separation anxiety. How more of an appropriate to make her feel more secure by being there for her when she is feeling abandoned (basic developmental psych). There is a reason why CIO does work, I wouldn't agree that it's a healthy one though.
I have 3 kids. My husband and I raised them to go with the flow. With #2 & 3 I used a sling to carry them around more. Since there was more to get done, and others to care for, I needed a way to be able to care for them as well as getting things around the house done too.
a few brands are lucky baby, peanut shell, ultimate baby wrap, baby ergo, hot sling, etc.
hang in there and go with your instincts.
