Here are some other suggestions to help you avoid over-feeding your baby during her first year of life:
Don’t automatically give her more. Resist the temptation to keep feeding her until she refuses to take any more. Remind yourself that she doesn’t have to be “full” all the time.
There is a difference between having enough to eat and being full. She doesn’t have to be so stuffed she cannot swallow another drop.
Your baby‘s inability to speak doesn’t stop her from expressing herself to you. Instead of words, she uses body language to 
communicate her feelings, thoughts and desires.
Look for language in her physical movements. Your baby tells you she has a tummy ache by drawing her knees tightly up to her stomach. You can tell she is relaxed when she lies flat on her back, gazing wide-eyed at the musical mobile.
Facial expressions are her way of communicating emotions. Psychologists have identified seven basic facial expressions that adults are capable of generating- unhappiness, joy, surprise, interest, disgust, terror and rage. Your baby too has enough control over her facial muscles to create all of these facial expressions herself.
