Some advantages to being twins are that the twins have a sibling their age, may understand each other better and can have a strong bond while some disadvantages are that they may often be compared to each other and not viewed as individuals. Identical twins occur when one fertilized egg divides into two, and these twins have the same genes. Fraternal twins occur when there are two fertilized eggs; these twins share half of the same genes and can be different sexes.
Twins can often have strong bonds between each other, understanding each other in ways that other siblings or parents may not. However, it is important to see twins as individuals with their own distinct personalities. Ways parents can achieve this is to spend time with each twin individually, give them their own space and give them separate gifts based on their own interests.
