That’s “push” as in, “I the mother, having been through the wringer and pushed out this blessed event, hereby claim my reward.” Or “push” as in, “I’ve delivered something special and now I’m pushing you, my husband/boyfriend, to follow suit.”

“It’s more and more an expectation of moms these days that they deserve something for bearing the burden for nine months, getting sick, ruining their body,” said Linda Murray, executive editor of BabyCenter.com. “The guilt really gets piled on.”

A recent survey of more than 30,000 respondents by BabyCenter.com found that 38 percent of new mothers received a gift from their mate in connection with their child. Among pregnant mothers, 55 percent wanted one. About 40 percent of both groups said the baby was ample reward.

Sandra Miller of Arlington, Mass., is not among the 40 percent.

“Women can and do expect a thoughtful token of appreciation,” she said. “It’s a way to honor a mother giving her emotions, body and hormones over to a baby for nine months, culminating in an experience which, when done naturally, redefines the meaning of pain. And when not done naturally, it’s still an act of sacrifice.”

Push presents seem to have taken off within the last decade, particularly in the last couple of years. In 2005 the Southeast-based jewelry chain Mayors marketed diamond earrings with the tag line, “She delivered your first born; now give her twins.” Fortunoff, the jewelry and gift chain with a Fifth Avenue flagship, established a push present registry six months ago.
