My youngest attachment-parented kid of 5 children has been sleeping around.
Around the house.
And I want you to know that this is going to happen to you someday, at your house. Tell your husband this is going to happen and have him read this. But you only need to show him this if he is a naysayer and thinks your baby or toddler who is sleeping in your bed and is attached to your breast nonstop is soon going to be a teenager who still sleeps in the shape of an X in between the two of you. You might also want to send this link to your mom, mother-in-law, sister, neighbor, and/or friend who think you are hurting your kid by sleeping with him.
We started attachment parenting in 2001 with our first kid. I say "we" because my husband was supportive and that is VERY important. Having a kid really tries a marriage and being on the same page with anyone about anything most of the time is hard, let alone when you are dealing with an extra human life in your house that is so very easy to mess up. (aren't we all messed up a little bit, in some way? nobody gets out totally healthy)
