Choosing a big sister or big brother shirt
Think about how you're sharing the news. For a pregnancy announcement photo, Notice of Promotion and Only Child, Best Before do the talking. For the hospital visit or the first weeks at home, Baby Security Detail and I Was Here First give the older child a role and a little pride. Big sister and big brother shirts help a toddler feel part of the big change.
Matching the new baby
Sibling Depth Chart lines up the whole crew, from oldest to newest. Some designs are family sets, so the big kid wears one line and the baby wears another, each picked from a list. A design here lets you type a name or a year, handy for marking the baby's arrival. When the big kid starts school, our Back to School Shirts are ready.
Sizes and colours
Look for toddler and youth sizes on each design, with baby sizes for the newest arrival on many of them. Parents can join in with adult tees, hoodies or women's fits. Choose matching colours for photos, or let each child pick. Order just one, or the whole family. For more, see Baby Shirts and all Kids & Baby Shirts.
Questions and answers
Do big sister and big brother shirts come in toddler sizes?
Yes, many designs come in toddler and youth sizes, with baby sizes for the new arrival. Sizes and garments vary by design, so check the options on the one you like before adding it to your cart.
When should we order a shirt for a pregnancy announcement?
Plan around your photo or reveal date. The delivery date shows before you check out, and if the shirt has to arrive by a certain date, you can choose a guaranteed delivery date at checkout for an extra fee.
Can the baby match the big sibling?
Yes. Family sets let the older child wear one line and the baby another, each picked from a list. The whole family can be ordered together, and the price per shirt drops as more shirts of a design are added.
