Which names sit near Kai?

These share gender and overlap on style or origin. They are a second look, not a ranking. Open the one that still works with your surname. Keep two or three, not twenty. Then leave the print aisle until sleep and the car seat are done.

What should you buy after you shortlist Kai?

Sleep space and a legal car seat if you drive, then a few 0–3 month cotton sleepsuits and a gift that works at 3 a.m. Skip nests, name-print blankets sold as safer-sleep, and a wardrobe of newborn-only knits. Official sleep advice stays free. Retailer hops below are labelled.
