The Baby (4–12mo) stage

The one big seat that grows with your kid from rear-facing newborn to forward-facing preschooler, so you buy once and stop thinking about it.

The high chair is command central for the gloriously messy months of starting solids, so we looked for seats that are safe, wipe clean fast, and don't hog your kitchen. Here are six real, current picks parents actually buy - from a $20 IKEA workhorse to an heirloom wooden chair that outlasts the toddler years - plus honest notes on who should skip each one.

The unglamorous purchase that saves your sanity once your baby starts moving: we sorted the pressure-mounted, hardware-mounted, and extra-wide options so you know exactly which one belongs at the top of your stairs (and which never should).

360-degree seats that spin toward the door so you're not folding yourself into the backseat to buckle a floppy newborn. We weighed how easy each one is to install, how safely it holds a rear-facing baby, and how long it'll last before you're shopping again.

The best double strollers for twins and two-under-two — from convert-later singles to budget tandems and doorway-friendly side-by-sides, honestly ranked on safety, value, ease, and how long they'll actually last.
