Age-appropriate toys for a baby that is 4-6 months old

Hello. In addition to the swing, floor match, and tummy time water toy, I’m seeking to acquire my kid a few other toys. Any recommendations? Our little one-bedroom apartment is small. Thus, not a lot of space. We’re about to move.

It seems that the Fischer-Price kick and play piano is the center of a whole cult. To find out if it lives up to the hype, I intend to add one to my baby shower list.

Since my fan theory article, I have taken the cult’s leadership role. The FP piano kick and play is amazing! Not even close to being knockoffs.

Is the kick and play piano on its own or part of a play gym? Cos we already have a play gym and my fiancée will kill me if I buy another lol but I really want the piano!!!
