The idea is great, the implementation is rather bad

My daughter is now 3 months, and you adjust the socks unfortunately barely even slip down again. The wrist rattles are for slightly larger, I think by the 5th month that still fit with the best of luck. According pack specifying these rattles are recommended only 0-3 months. The rattles for 3- 6 months, and 6 - 12 Months old children are not yet available, unfortunately here on Amazon, will therefore have to look for it elsewhere.
Otherwise, the fabric colors are really great and the characters (beetles, butterflies) look really sweet. The processing of seams are also super. My daughter likes the wrist rattles particularly, even if they are too low for a baby ear almost back.
But I would recommend the combined rattle already on, just ask the seller to write out a better indication of size!
