It’s normal to feel overwhelmed as a SAHM, especially with no helper or in laws to help. Our job don’t have off days, don’t have proper lunch breaks, don’t have proper toilet breaks, especially if baby is those that cannot stand seeing you taking a break (like mine).
Household chores falls on us, baby needs us 24/7. People always think that we have nothing to do since baby sleeps all day. Baby sleep, we need to do housework, need to pump, when finally done, baby wakes up. When you finally get to eat a proper dinner, they say you enjoy life. No one sees all these, all they see is “she stay home shake leg, wait husband feed.” And husband’s thinking is “stay at home, of course household chores and baby is your job because I’m feeding you.”
Because we’re with baby 24/7, we experience all their meltdowns. People only play with baby for a short period of time so they think baby is an angel, easy to take care. When baby sick, who stay up late and keep waking up to take care? Naturally all thrown to the one “staying at home”.
Plan a trip with your friend/solo, like a 3D2N, inform your husband the dates, ask him to arrange his leave and leave, let them experience what you’re going thru everyday to see if it’s really nothing to do. I think by day 2, your mil will be at your place already.
For your sister, no need to bother about her. So only working then got the rights to feel tired? Try asking her work 365 days, 24/7 at office then. Unless you’ve been thru the same situation, you have no rights to judge or comment.
