Well Dr Sears should get out of his little privileged bubble more. My mom would have loved to have nursed me. She couldn’t. She barely produced any breast milk. Was she a terrible mother? Not at all. She was and is an awesome mother. I pit my bond with her against the bond of any breast fed person on this planet!
I believe that Sears has a skewed perception of what family life is like for most people, and he certainly advocates for practices like breastfeeding, bed sharing, and baby wearing, occasionally going so far as to present misleading citations to “scientifically” support his beliefs.
However, I don’t think he actually says that moms who don’t do X, Y, or Z are bad mothers. In fact, my recollection of his original statement coining the term Attachment Parenting is that he says something like it’s all about being responsive to your baby. Has he gotten more into the “AP checklist camp” since, and can a reader infer from his writing that he thinks mothers ought to do X, Y, and Z? Sure. But I think he’s just like every other parenting “expert.” If you read their books taking everything they say as gospel, you’re making a mistake. I didn’t believe Sears when he implied that I shouldn’t even try to regulate my kid’s night-nursing until she was 2, just like I didn’t believe Marc Weissbluth when he said that my child would be a lifelong insomniac unless I dropped her in a crib and let her cry for hours.
While the title was chosen to be provacative as much as the picture, I don’t think Time was actually advocating that position. They were describing the Attachment Parenting paradigm, and the position advocated by Dr. Sears.
My daughter (an unwed mother at 19; baby now 17 months and doing great) was really offended by that cover title, “Mom Enough” She tried breastfeeding - it didn’t work. (Worked really well for me. I should have been a wet nurse.) Anyway, she’s doing a great job in a very rough situation, on her own. Kept baby out of day care for first year. That baby is so happy and well adjusted, so far. I would hate for any other mother or doctor to judge her.
Did you read the article or is that just a guess?
I read the online material from the OP, that described the photographer’s decisions and intent. I did not read the article.
OK. I read that summary too and didn’t see anything in it about how attachment parenting = “are you mom enough?” (I haven’t read the actual article either.)
It made me ill. I was bottle fed. 
The cover picture has the article title, subtitle:
I take that as a summary of what the article will be about. Describing their actions as “extremes” suggests the article is going to not be advocatory, but descriptive.
I really really really really want to know the context of that picture.
