A lot of parents are in a hurry to have their babies grow up. Thinking ahead about walking and talking and potty training and learning. It’s important to be present, fully present, with every stage of development and not get ahead of yourself or your child. Raising kids is not a competition and a lot of moms get into a competitive mode, whose baby was toilet trained first, walked first, talked first and are wanting to put their infants/toddlers in play groups well before the child has any concept of playing with or sharing with other children. IMO toilet training shouldn’t start until the child is 2 years old or more and play groups are complete nonsense until around age 3 in most cases.
Don’t be in such a hurry to take away their bottles, pacifiers, diapers, security blankets and thrust them into social situations they have no ability to cope with. My daughter still had her bottle until she was around 16–18 months old and wasn’t fully potty trained overnights, until 3 and still slept with her favorite blanket until she was about 7. Who cares whose kid did what first at what age? Who cares if they still get comfort from sucking on a bottle at 18 months?
Who cares if they want their security blanket until they are 5 or 6 or 7 or 8 or walked at 10 months or 14 months? WHO CARES!
Let little kids enjoy being little without all sorts of adult pressure to do something on some rigid time table just to stroke mom and dads ego and give them bragging rights.
