Mini Arch Magnetic Wall Decal in Maple Latte

Sizing varies a lot between children's brands, so the single most reliable guide is the size chart on each individual product page. The reference below covers how sizing generally works across the brands we carry at Shop Little Cousins.

Baby sizing (newborn – 36 months)

Baby clothing is sized by age in months. Most brands size up, meaning a garment labelled 6–12M is cut to fit a baby up to 12 months old.

• Preemie – up to about 5 lbs
• Newborn (NB) – about 5–8 lbs, up to 21.5"
• 0–3M / 3M – about 8–12 lbs, 21.5–24"
• 3–6M / 6M – about 12–16 lbs, 24–26.5"
• 6–12M / 12M – about 16–21 lbs, 26.5–29"
• 12–18M / 18M – about 21–24 lbs, 29–31"
• 18–24M / 24M – about 24–28 lbs, 31–33.5"

Toddler and kids sizing (2T – 10+)

After 24 months, sizing switches to numbered sizes. A "T" size (2T, 3T, 4T) is cut for a toddler still in diapers and is generally roomier through the hip than the equivalent numbered size.

• 2T / size 2 – about 2 years, 33–35"
• 3T / size 3 – about 3 years, 35–38"
• 4T / size 4 – about 4 years, 38–41"
• Size 5 – about 5 years, 41–44"
• Size 6 – about 6 years, 44–47"
• Size 7 – about 7 years, 47–50"
• Size 8 – about 8 years, 50–53"
• Size 10 – about 9–10 years, 53–56"

Brand notes

• European brands such as Mayoral are sized in months and years using European measurements and often run slimmer and longer than US brands. If your little one is between sizes, size up.
• Organic cotton and ribbed knits have more stretch and are more forgiving between sizes.
• Two-piece sets and pajamas are usually cut with growing room. Snug-fit sleepwear is intentionally close-fitting for safety and is not undersized.
• Maileg toys are sized by mouse size (Micro, Baby, Little, Big, Mum & Dad) rather than by clothing size — each product page lists the height in centimetres.
