Seeking advice: Move w/kids from SF to Oakland (Trestle Glen)

We’re planning to move from San Francisco to Oakland in January with our newborn and 2.5-year-old. We’ve narrowed down a house in the Trestle Glen/Lakeshore area (near Petco and Trader Joe’s on Lakeshore Ave), and I’m looking for advice and community support.  

1. Safety & Crime: Can anyone share insights about safety in this neighborhood in general?  

2. Kid-Friendly Activities: hoping to find fun options for both our little ones, like infant/toddler swim classes, toddler music, or dance classes. Are there any favorites in the area? Other suggestions are also welcome!  

3. Preschools: We’re searching for a preschool for our oldest, ideally one with a mix of forest and conventional learning (a forest school with physical classroom time). Any recommendations?  

4. Other Facebook or online community groups to join for Oakland related info?

Thank you so much for your help!
