Hi M.~
I have an idea for you. It is called the "Yes, Mommy Game"
-Tell your child you are going to play the yes, mommy game. Remind them that when you call your child's name, they are to say "Yes, mommy, I'm coming!" And come right away and look at your eyes to receive instruction.
-Have your child go in a different room and wait for you to call them. Bis hugs &lots of praise when they come when you call.
-Do this for about 5-10 minutes, make it lots of fun.
-Tell them to listen throughout the day for you to test them and remember to do it. If they don't come when tested, play the yes, mommy game for a couple minutes as a reminder then test them again.
Let me know if it works. It has done wonders for me! :)
