Three kids under three= Advice in need

li

Hello! I just found out on Monday that I'm between 3-4 weeks pregnant with our third baby, this wasn't planned at all, we have a 2 years old boy and a almost 6 months old girl, I got pregnant because I didn't check when my fertile week start, anyway this baby is supposed to come at the end on August. I know is way to early to be asking for advice but I'm asking this for people that is somehow in my situation or has kids that are close in age,how do you handle kids being so close in age? How do handle the house work? I just want to be prepared for this, I will cook a lot and freeze a lot when the due date is closer. I'm just looking for feedback so I don't loose my mind. TIA
