I have to go to the dry cleaner, but I have this baby. Can't leave it in the car. Awkward to carry carseat and dry cleaning in together. Cumbersome to take stroller out. Don't even get me started on that sling.
I pour milk in my cereal and baby starts crying. Leave cereal to get soggy? Leave baby to hyperventilate?
I'm sleeping. Baby has gas. Aid baby with expulsion of gas? Continue sleeping? Try to force Chris to aid baby with expulsion of gas, given that he's going to work the next day, but also given that I haven't slept more than three hours straight in two weeks?
