Asking for a diaper size can feel awkward. Here's how to do it politely, what to say if guests answer 'surprise', and why a digital invitation makes it easy.

You're at a baby shower. A guest arrives with a giant box of newborn diapers. The baby is already in size 2. You smile, say thank you, and quietly wonder where you'll store 200 diapers that will be outgrown in a week. It's not the guest's fault. No one told them the baby shower diaper size.
Telling people which diaper size you need can feel like asking for money. It's not. It's logistics. And with a digital invitation, you can ask without the awkwardness. Here's how to do it politely, what to say if guests answer 'surprise', and why the right channel matters as much as the right words.
Baby Shower Diaper Size: It's Not a Gift Request, It's Logistics
Diapers are the only baby gift that expires in weeks. A newborn size fits for a few weeks at most. If you don't say which size you're using, every guest guesses. You end up with a mountain of newborn diapers and none in size 3. Asking for a size isn't rude. It's making sure the gift gets used.
- Newborn diapers fit for a few weeks. A baby in size 2 can't wear them.
- Without a size, guests guess. You get 200 newborn diapers and none in size 3.
- Diapers are the one gift that expires. You can't store them for later.
- Asking for a size isn't asking for money. It's making sure nothing goes to waste.
How to Ask for Diaper Size Without Sounding Rude
Instead of 'bring size 2 diapers', try: 'If you'd like to contribute to diapers, the size we're using is 2.' Always add an exit: 'Your presence is what matters. If you also want to bring diapers, this is the size that helps us.'
Turn it into a closed question: 'Will you help us with size? Choose: NB, 1, 2, or 3.' If someone says 'surprise' or 'I don't know', offer a wildcard. Size 1 or 2 work for the first weeks. Or suggest a voucher: 'If you prefer, choose the size you would use and we'll exchange it.' Don't insist. If they want to keep the surprise, thank them and let them bring what they want.

Asking for a diaper size isn't rude. It's the difference between a gift that gets used and a pile of newborn diapers.
Timing and Channel: Where to Ask
Don't ask on WhatsApp at 11pm in the family group. The message will get lost between memes and opinions on the baby's name. Wait until the date and place are confirmed. Asking before the official announcement sounds controlling. And when you do ask, centralise it. A digital invitation puts the question where guests already are: in the RSVP form. They see it when they confirm, not when someone forwards a message.
