My little 21 month old has become easily frightened in the past few days. When he hears footsteps upstairs, for example, it's "mamamamama!" and jumping into my lap. We live an apartment so this is normal!

I am not sure if this has to do with his age or maybe the fact that he'll be a big bro i the next few weeks (something I'm not sure he understands but may generally sense). Any insight? Did your toddler go through a scaredy cat phase?
