20 weeks and starting to believe I am in the early nesting mode

So I am 20 weeks and 3 days and since Saturday I have started what I defined and early nesting mode. Could it be possible ? This is my 4th pregnancy, would be having a 9 and a 7 year old and almost 11 month old around when baby is here 🤦🏻‍♀️ that wasn’t planned but God had other plans. So Irish twins would be.

How early have any of you guys started to get ready like getting house baby x2 ready 😂 and all of the other stuff. This weekend God willing we will begin to buy diapers and wipes to get stock enough in case for both babies.

Have some baby boy clothes, car seat and stroller, would just need a playpen for baby to sleep and other little things. Is it too early I mean we are only 4 months away ?
