Quick answer

For most families, start with the Great Lakes Loons Bimm Ridder Infant Velcro Bib for messy days and the New Era Alternate Green 9TWENTY Adjustable Cap for game days. Add a youth long sleeve like the 108 Stitches Cotton Candy shirt when you want extra coverage without a heavy layer. If your child prefers a standard tee, the Baseballism Battery Up Bakery Tee is a simple, low-cost option.

Match the garment to the mess and the weather

Babies and toddlers create two kinds of messes: food and weather. A bib handles the first; a long sleeve or tee handles the second. The Bimm Ridder Infant Velcro Bib uses a 60% cotton, 40% polyester blend, which balances absorbency with quick drying. That blend is a practical middle ground for purees, spit-up, and sticky fingers. For cooler game days, the 108 Stitches Green Cotton Candy Long Sleeve is made from 50% polyester, 25% cotton, 25% rayon, a mix that feels soft and adds warmth without bulk. If your child runs hot or you are dressing for a summer afternoon, a 100% cotton tee like the Baseballism Battery Up Bakery Tee is a breathable alternative.

Sizing rules that save you a return

Youth and child sizes are not the same as baby sizes. The New Era 9TWENTY cap comes in Adult, Youth, Child, and Toddler sizes, so you can match the cap to your child’s head rather than guessing. For shirts, the 108 Stitches long sleeve and the Baseballism tee are listed in youth sizes, with the tee available in S–XL. If your child is between sizes, size up for the long sleeve so it lasts through the season; for a one-season tee, stay true to size. Always check the product page for a size chart before ordering, because measurements can vary by style.

Fabric trade-offs: what to expect

Cotton feels soft and breathes well, but it can shrink and wrinkle. Polyester adds durability and helps stains wash out, while rayon adds a smooth drape. The bib’s cotton-poly blend is easy to rinse, but it is not fully waterproof, so it works best for meals, not for full-on water play. The long sleeve’s poly-cotton-rayon blend is comfortable for air-conditioned concourses or evening games, but it may pill if washed with rough items. The 100% cotton tee is simple and breathable, but it will show stains more readily than a poly blend. None of these garments are described as stain-resistant or waterproof, so plan accordingly.

Layering for game day

A bib, a cap, and a long sleeve cover most of the season. Start with the bib for the youngest fans, add the adjustable cap once your child can keep it on, and choose the long sleeve when the temperature drops or the sun is strong. The 9TWENTY cap has a flexible crown and adjustable closure, which helps it stay put during wiggly innings. If you already own a Loons tee, the long sleeve can layer over it for extra warmth. Keep the outfit simple: one logo piece is enough, and a matching cap ties it together without overdoing it.

Decision rules for buying Loons baby and toddler gear

  • If your child is under 2 and still in a high chair: Choose the Bimm Ridder Infant Velcro Bib as your first purchase. It is sized for infants and the Velcro closure is quick to fasten. Buy one to start; add a second if you want one in the wash and one in use.
  • If you need a cap that will last more than one season: Pick the New Era 9TWENTY Adjustable Cap in Child or Toddler. The adjustable closure and flexible crown accommodate growth. Measure your child’s head before ordering and size up if they are between sizes.
  • If your child runs warm or you attend day games: Choose the 100% cotton Baseballism Battery Up Bakery Tee for breathability. Save the 108 Stitches long sleeve for cooler evenings or air-conditioned spaces. Cotton shows stains more easily, so treat messes quickly.
  • If you want one outfit that works for most of the season: Combine the long sleeve with the adjustable cap. The long sleeve adds warmth without bulk, and the cap provides sun coverage. This pairing covers spring and fall games; add the bib for younger fans.
