I put my son very early on the mat (1 month and a half), first simply by putting it in his recliner or on maternity cushion and sliding it under the arches for a small time awakening. That way, he had access to tucking. The musical caterpillar and light was fascinated right away. The music is quite nice to listen to them for several months now. There are several toys, rattles, stuffed animals (frog, beaver) and mirror, so plenty to discover for baby. In addition, the mat comes in a plastic bag very convenient transportation. It is true that the carpet is thin, I bought a quilt for 5 loss in Eurodif I placed below. Excellent purchase, I highly recommend it.
