Caring for two kids

If you just recently had your 2nd baby, How are you holding up caring for two kids at once? I just had my second baby 3 weeks ago and today my husband went back to work (he’s been caring mostly for our toddler while we adjust) I’m wanting to know how everyone handles two kids at once? Especially toddlers and newborns. I feel so incapable and I am getting overwhelmed so easily.
