Come winter, you’re like the mailman. Neither snow, nor rain, nor gloom will keep you from delivering your little parcel to music class.

And considering how the mercury rises and falls with unseasonal abandon — that’s a tall order.

Allow us to introduce the Baby Shield. The latest innovation from 7 A.M. Enfant comes with two covers — a heavyweight quilted barrier for the most frigid days and a waterproof wind guard for more moderate temps. Easily interchangeable, the two options zip on and off faster than the jet stream dipping in from Canada.

Both covers can also be used independently as blankets (elastic straps hold them in place), for days when you make a last-minute switcheroo between stroller and car seat with no time to move the whole muff.

It’s just the thing to keep your tot going all winter. And keep you from going postal.

Available at Heights Kids, 93 Pineapple Walk, at Henry Street, Brooklyn Heights (718-222-4271); online at 7amenfant.com, $179-$219.
