I balanced my crying newborn on my hip and tried to get my shoes back on while still tangled in the baby carrier. As I hurried to collect our SEVEN trays of personal belongings speeding down the conveyor belt, my makeup was melting down my face. My husband was getting electronically frisked, so I was single-handedly holding up the hundreds of other travellers who were wondering if - sigh - I'd be on their flight.
If your child is sick or if you hear a cry that is not "normal" for your child, do not hold yourself back from responding in a way that you love responding to your child and in a way that your child needs and loves.
Follow what your heart and intuition are telling you that your child needs. Do it. You will not ruin sleep forever by doing so!
