I'm a mom of two toddlers 2&3yrs my 2 yr old knows baby is in my tummy idk that she fully understands but she kisses my tummy lays her head down on my tummy talks to baby But weird thing to me is like the last two weeks she been all over my breasts. I dress modestly and keep them covered but she keeps trying to touch them, lay on them,and gets upset when I won't let her. Is this normal? Why is she doing this? I just don't understand.
