Newborn, toddler, pumping

Hi Super Mummies, How do you manage? I’m extremely sleep-deprived and can’t seem to find the time to rest. Need to pump every 4-6hrs otherwise I will feel engorged. Can’t do 2 hourly as time is restricted. Everytime I think I can rest, I need to pump or feed either toddler or newborn. It’s crazy hectic. I’m going bonkers and I’m a SAHM, my toddler is 1y 10m and is not in school yet. Living with my parents and in-laws while waiting for my BTO. I do have help but I try to do it myself as I want to get used to being alone with my kids when we get our house. I can’t seem to function everytime I wake up with 1-2hrs sleep. My 2 weeks old newborn is also colicky and is demanding for a feed every 1.5hrs - 2hrs. I really pity my firstborn as she doesn’t get as much attention as before. 😣 Care to share how’s your daily schedule like?
