Work at home moms

Jessica • Married to my main squeeze for five years. Momma to two feisty girls (8 months & 4years).
How are you preparing clients or boss for your maternity leave? I really don't have a boss that can designate my work to anyone else as my clients are solely mine. I'm so overwhelmed and do not know how to refuse work for a few weeks to adjust to being a stay at home mom of two.
