Who’s to say that had I weaned him he wouldn’t be “sticky” to me right now? And who’s to say that weaning him would have had any effect on his current behaviour. For all we know, he could be even worse than he is right now. And if I had weaned him, he may have felt even more jealous of his brother’s nursing time. My friend who did not breastfeed her daughter also found her daughter to become more demanding and more “sticky” after she had her second child. Her daughter also displayed all the classical signs of sibling rivalry.
