I like to think of myself as an accomplished woman with lots of fulfilling professional and personal relationships. My now-toddler, by contrast, appears to think of me as his own personal milk-and-cuddles machine. That would explain the look of utter surprise, followed by serious irritation, when my baby sees me kiss my partner. He was not on board with this at all, and like any strong-willed person, he made his displeasure known. At around six or seven months of age, my son would swat at my husband if he tried to touch or kiss me while my son was nursing. By ten months or so, my son would throw a full-on stiff-arm my husband’s way any time he'd try to hug me if he were in my arms, actively pushing us apart. Sorry, Daddy, but you seem not to understand life on Planet Baby. You hug me, or Mama hugs me. Everybody hugs me. Nobody hugs each other.
I can't say I blame my son for being a little confused. He was (still is) pretty new around here, and based on his limited data points I could see how he came to the conclusion that my affection only belonged to him. We spend most of our time together, and he definitely gets the lion's share of my affection during our overlapping waking hours. Because he used to sleep much more often (however erratic), and I typically only had time to be affectionate with my husband when he was sleeping, my relationship with my husband — independent of my son — is completely beyond his awareness. So, when he started spending more of his time being awake, and began seeing aspects of daily life in our home that had nothing to do with him, it definitely seemed to take him by surprise.
Recently, though, he has started to warm up to the idea that the larger humans in his life can have relationships with each other, and that mama can be affectionate with many of the "Not-Mama" people in the world, without threatening the overall amount of cuddles and other attention he receives. He has even started coming around to the idea of group hugs, but only when he initiates them. Babies can be a little possessive at times, but it's pretty funny to witness their thought process (and chubby-fisted defensive moves) when their number one is at risk of paying attention to someone who isn't them.
