So my son has grown very very attached to his Daddy. To the point he follows him everywhere, cries when he leaves, waits up till 3am for him to come home or he has a hard time falling asleep. Its the cutest thing but when he leaves for work my son is super upset.. Which is the only time he will cling to me. But if Daddy's home you can forget it lol Anyone else have this issue??
