The small bibs can be worn from birth, they are perfect for preventing drool or small excess or regurgitates from ending up in the neck and thus avoiding irritation. They are also pretty, and preserve clothes during periods of drinking (breastfeeding) or when baby is teething.
the bibs adjust with 2 snaps so they will be useful for a long time and they are solid so baby cannot remove them easily
For the trios, the secondary colors may vary depending on availability but they will match your main choice (so in the trio there will be one of your chosen theme, for example elephants, a plain one without patterns, and one with simple patterns, dots, lines...)
