Young children may become distracted by the new baby and forget to make it to the potty. They may also wish for a simpler time in their life when they received extra time with mom or dad on the changing table.
Moms who breastfeed may find their older child trying to crawl into their lap, hang from their arms or shoulders, nudge the new baby while nursing, or ask to nurse themselves. Similarly, older siblings may ask for a bottle and/or pretend to suck from a bottle.
It can be very difficult to tolerate seeing the intimacy of the connection and the time spent between a parent and the newborn, and the older sibling may very well want to be included in the attention.
