My daughter is 2 1/2 yr old, she is obsessed with holding my nipple (since breastfeeding) which stopped at the age of 1yrs old. I don't let her do it in public although she does try but she won't stop until she can do it when she goes to sleep, she will get very irritated or upset or tantrums or she won't go to sleep if I say no. Anyone else experienced something similar?
