Your baby has been rigorously practicing reaching and grabbing, and with all the swatting at toys, they have finally been able to successfully reach and grab (on average starts around 4-5months)and maybe even do this consistently and in a very controlled fashion(starts around 6-7months). Continue to let them hone their skills through fun practice of reaching for what they want. This also stimulates their sense of vision and touch!
Offer a variety of objects that differ in size, shape, and texture. Let her feel what it is like to hold a smooth ball versus an object with corners; a small toy that she can easily hold in one hand or a larger toy requiring to use two hands; a toy that has different parts that dangle versus a solid object, to name just a few examples. Be careful not to overwhelm her with too many toy options. Pick 3-5 toys on which she can focus. Who knows, she may even reach for 2 toys for each hand!
