Nanny Needed - Full-time / Part-time

Looking for a nanny/ babysitter for a newborn. No cooking, cleaning, errands, or pick-up/drop-off is needed. We are flexible with work hours but are hoping for 4-5 hours per day (around 8am-noon) Monday-Friday, starting in September. Home has no pets and is non-smoking. Must be a non-smoker. We are allergic to cats. Our baby has bad acid reflux, so feeding can take up to an hour (paced bottle feeding and sitting baby up after feeds for 20min+).
