Product Recommendations for Baby #2

My daughter is will be 4 in August and baby #2 is due next Winter. What are the must have for #2?

Definitely need a solid double stroller - my toddler is on the smaller side and loves her stroller, so will definitely use it for 2 kiddos for a while until toddler outgrows it. Appreciate recommendations in this department as well

Thanks!

TIA
