I feel you! My 1-month old wakes up every 2hrs for feed every night so we’re definitely sleep deprived. Can only do housework or even eat and rest when baby sleeps, and got to do them quickly. I’m staying with my MIL but she doesn’t help me much. Very tiring indeed when you got to do everything on your own. I even cried a few times cause it was too overwhelming. But somehow over time, you’ll get used to the routine. Talk to a fellow mummy friend so you won’t lose your sanity :)
