Peaches Geldof's youngest son was with her when she died.
The 25-year-old star's husband Thomas Cohen - who had spent a night away with eldest child Astala, 23 months - asked a friend to check on her at their home in Wrotham, Kent, South East England, when his wife failed to answer her phone on Monday, and her body was found with 11-month-old Phaedra playing nearby.
A source said: "The hope is that Phaedra is so young he wasn't aware of what was going on. The most important thing is that he's OK.
"It is devastating for Tom that he wasn't there but it couldn't have been avoided."
Peaches was an advocate of attachment parenting, meaning she was rarely without her young son by her side, and insiders hope her family will take "comfort" from the fact she didn't die alone.
The source added to The Sun newspaper: "Phaedra was by her side most of the time, even when she was sleeping. At the very least, there can be some comfort that she wasn't by herself when she died."
When Peaches' own mother Paula Yates was found dead at her London home in 2000, her baby daughter Tiger Lily, now 17, was found playing near her mum's body.
Yesterday, the presenter's father Bob Geldof was seen visiting her home, where he was greeted by Tom's parents Keith and Susan. The two men spent 20 minutes talking in the garden before the rocker entered the house, leaving two hours later with some of his daughter's belongings.
Peaches' body has now been released by coroners so plans for her funeral can be made.
Her cause of death remains unexplained.
