When you have an infant there isn’t much high level learning going on but sensory stimulation is important and this Loopy Ball fits the bill. The bright colorful fabric catches the attention of infants and they respond. Of course based on the age of the baby the reaction will be different but when they reach the age where they can reach out and grab things, they certainly grabbed hold of this. The various rings made it easy and helped advance their manual dexterity. A great toy to have available during supervised tummy time.

They told us that it was large enough that it didn’t get lost in a pile of toys yet compact enough to grab as you are running out the door to keep baby entertained. A final note about how easy it is to clean, in a word, very.
