Here’s how Monica + Andy fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s Monica + Andy size on the left. Twins wear the same number the same way — your size carries straight over. Strangers use the same number but cut it shorter or longer, so don’t trust the label alone.

Where the number just works. At 0-6M, 0-12M, 3-6M, 6-9M, 6-12M, 9-12M and more, Monica + Andy lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 4T, Tommy Hilfiger Kids, Kyte Baby, Magnetic Me cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Monica + Andy number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Which trimmer, roomier, or adaptive cuts Monica + Andy publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Monica + Andy’s own published chart; the notes here come from public parent discussion.
Monica + Andy runs generous — the consensus is “runs large,” which is typical of GOTS organic cotton cut roomy and prone to a mild wash shrink. The dominant advice from parents is to size down for older babies and toddlers if you want an immediate fit, since a size often lasts well past its stated age range (one parent: an 18/24M “will fit her through 2T”). A minority find certain pieces slightly snug through the thighs and waist, so it isn’t perfectly uniform style to style. Shrinkage is mild and predictable rather than alarming — one set “seemed very large when it arrived but shrank when I washed it and fits perfectly” — and prints are reported to survive hot washes without bleeding. Softness and the organic-cotton quality are near-universally praised; the loudest complaints are about shipping on the brand’s own site, not the clothes. Plan for generous-but-grows, and wash before you judge the fit.

Slightly and predictably — it’s organic cotton. Pieces often arrive roomy and settle to a good fit after a wash rather than shrinking out of usable size, so wash before deciding on fit.
Parents who value organic/GOTS fabric, softness and multi-kid durability say yes. If you only want cheap basics, it’s a stretch.
It’s positioned like Hanna Andersson — premium organic cotton cut generously with room to grow — rather than the stretchy, snugger bamboo fit of Kyte.
Monica + Andy publishes height, weight in its size chart. Height is the primary driver on this chart.
Monica + Andy’s socks are sized by shoe size, not age — buy for your child’s current shoe size, and if they fall between two ranges choose the smaller so the sock stays up. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
