Keeger:Have you tried a sling, wrap or some other type of carrier instead of the stroller. Maybe your baby would rather be closer to mom.
That's a good idea! They can be kind of expensive so try a kid's thrift store or ask another mom to borrow ones before you spend the money.
Maybe all the noise, colors, and sights are overstimulating her. Have you tried a less busy plaza or maybe the park?
