Your baby’s ability and eagerness to bend and pick up objects from around her signifies two important things. One, that she is eager to interact and engage with objects around her which goes on to show development of her curiosity, and two, that she is now physically fit and capable of bending her knees, squatting, grasping, and lifting objects.
From the 8th month or so, when your baby’s trunk has become stronger, and she has developed the confidence to sit up, she will also start leaning over to pick up objects while being seated. Once she has mastered crawling (some babies will not go through the crawling phase; instead resort to scooting on their bottoms to transport themselves), she will take baby steps (literally) towards standing up straight and then walking.
Bending is crucial at this stage, because once your baby has learnt to stand up straight, she will not be able to lower herself and sit down again. If she cries for your help, physically show her how to bend her knees so she can lower herself to the floor without falling. This will make her more independent and will greatly incentivize her to try out the standing-up experiment on her own, even when you are not around her. But remember to supervise your baby at all times and also to baby-proof her surroundings. This generally happens around the 9th or 10th month.
Somewhere between the 12th and 18th months, your baby will move a step forward and also try squatting. She will bend down to pick things that attract her attention and catch her fancy from the ground. Squatting marks an important development as it involves lowering herself only halfway to reach her desired objects. She needs good flexibility and support from her knee muscles and joints to manage this.
Parents should help their baby with this new trick of squatting. Show them how knees can be bent so they can imitate your moves. Also, you can keep your baby’s favourite toys and things around her so she has the urge to squat down and pick these objects up.
