Sounds like my son when he was the same age.I guess they started
to get more aware of their environment.He also doesnt like my husband(my husband started to worry) or anyone else.
The more you get your husband or other family member involve or help you the better.Early in am,when my son wakes up I let my husband pick him up, take care of him and change his diaper and play with him until he goes to work and I enjoy my leisure breakfast and coffee.The baby will get to know other scent beside you.
Take time to go out every now and then.Get a massage or go to a bookstore for an hour or two while other family member is watching your son.Enjoy a book and a cup of coffee for an hour or two.You need this to keep your sanity.Cause this will be a long journey.
Until now(my son is now 17 mos)he follows me around wherever ago.The only people he wanted to be with are the people I let him with when he was a baby (my husband and mother-in-law).I still
can't leave him to a complete stranger or he will cry.
So I know I have to do some weaning now before he goes to pre-school.Im starting to look into a reputable day care or mother's day out so I can wean him slowly with me.
