How to Deal with Attention-seeking Toddlers

Teach “The Squeeze”
Tell your child if she wants your attention when you’re talking to another adult, she should gently squeeze your arm. You can then squeeze her hand to show that you know she is there and that you will be with her in a minute.
At first, respond to her question quickly so your child can see the success of this method. Over time you can wait longer, just give a gentle squeeze every few minutes to remind your child that you remember the request.
