Help Just going back to work and starting BLW

So bad timing I know but little guy just turned 6 months and wouldn’t do purées anymore so we started blw today and I go back to work tomorrow....

What do I do he loved feeding himself today but I’m at such a loss for what to pack and I don’t want the mil or who is watching him to feed him whatever

Can I mix purées and baby led weaning if I get desperate or is that confusing to baby?
