Twins after singleton

Meridian

Yall we just found out we are 12 weeks pregnant with twins. Our son will be 16 months old when they are born and we are a little nervous to say the least about a lot lol. What are tips, tricks, products, etc that is recommended? I'm trying to especially find a baby stroller that fits two babies and a toddler and it doesn't matter the price but I would love suggestions. Thank you!
