From the crownheights.info site:
Pardon ask for asking, but is a cemetery really a place for toddlers and preschoolers?
"From writing to the Rebbe, making a hachlata, to giving tzedakah and wearing special shoes, very young children can become more aware of these important details, enriching their Ohel experience and strengthening their hiskashrus with the Rebbe."
Thousands of Tzadikim, Gaonim as well as the greatest and holiest Rebbes have passed away, but no one has ever suggested that young children be inculcated with such bizarre ideas which in their young minds could border on necromancy and "doresh el hameisim".
"A must for every Chabad home, I Go to the Ohel was developed with input from rabbanim, chassidishe parents, and preschool teachers."
What seems to be missing is input from expert child psychologists about the danger of distressing and traumatising young children by exposing them to death and graveyards. The alternative risk is that trivialising the cemetery "experience" in children's books totally removes the concept of "ma nora hamakom hazeh".
We fervently hope that the leadership in 770 will protest this improper and frivolous portrayal and interpretation of this makom kadosh - the resting place of the Rebbe zichrono livracha.
