Hold the Horses there.
Now this is just my opinion. Exactly, how old is that l yr old? Is she 12 months or 18 months? I did not force my daughters off the bottle. I let them take the bottle as long as they wanted. At this time, I don't remember if there was intermitment sippy cups or not.
My youngest daughter hung it up earlier than my oldest daughter. I knew that my oldest daughter was ready to give it up when I put the bottle in her mouth and she did
not want to suck on it anymore. That was 18 months. The oldest daughter graduated from CSU and my youngest daughter is in college and affiliated with the army. A toddler on a bottle is not a sign of a mentally slow child!
I had this psychological hang up that if I took away their bottle at an earlier date that they might want to find oral gratification through overeating or boozing it up at a later date. I felt bottle deprivation or the deficit of it could lead to trying to meet this deficit later in life. I don't know if there have been any studies on this.
Watch the Kool Aid in the cup. Toddlers don't need the sugar and artificial colors nor dental cavities resulting from the sugar. To hell with what the other mothers and kids are doing. Let your daughter enjoy her bottle as long as she likes. Sure, its a pain to clean and prepare those things.
But hey, WHOSE bottle is it to enjoy in the first place?
Your daughter will let you know when it is time to hang up the 'bah-ba'. Good Luck.
