The trustee should provide a copy of the trust to all beneficiaries right away. Yes she can wait for 60 days, but waiting really serves no purpose as it just creates problems between her and the beneficiaries. Trust administration related delays are probably biggest concerns beneficiaries have.
By the way, I don't necessarily view requests for estate documents following the death of a parent, acts of harassment. If you do, then encourage the trustee to send copies of the trust. Problem solved.
Sending a copy of the Trust to the beneficiaries is a requirement under the California Probate Code. It is not harassment for a beneficiary to ask for a copy -- They are entitled to a copy. You have a reasonable amount of time to do this. The estate tax attorney will probably want to send out a copy of the trust with the 120 day letters.

Technically, the Trustee's (the executor in your scenario) should send out a Notice of Irrevocability of the Trust, within 60 days of the death of the person who created the Trust. This Notice informs beneficiaries of the Trust that they have a right to request a copy of the Trust. However, once the beneficiaries have requested a copy of the Trust, the Trustee has a duty to comply with the request.
