It is important for parents not to follow into a pattern of negative behavior with yelling, spanking, and threatening of their own. Teach children names of body parts. Stress unique, individual qualities of the child. Teach concepts of please, thank you, and sharing with others. If not already reading to the child on a regular basis, this is a good time to start as it will enhance the development of verbal skills.
Girls usually are well into toilet-training.
Some boys may not acquire the skill until 3 years of age as their nervous system matures slower than girls. Attention spans are short and toddlers are distracted by and attracted to a wide range of stimuli . It may be easier to arrange for someone to stay with the child at home rather than always take a toddler grocery shopping with you.
