Buzzy's Balloon — Harriet Ziefert

And it's a balloona balloon that Buzzy can talk to, play games with, and have as a constant companion. Buzzy gets a little help from his mother when the balloon deflates, but has to find his own replacement when it bursts.

The Buzzy books help children explore their own feelings and discover solutions. Illustrated with great charm, this separation-and-loss story is sure to resonate with young children.
