Out of date biscuits!! Safe for lo?

Cass • Family first 💚
Just bought some orange chocolate digestives from the shop, they're pretty bad at restocking sometimes and I just checked the packet and they went off in October 2014!! I usually just use my head with this kind of thing but I'm unsure with biscuits? 😫
Bad news is my 4 year old helped herself before I could stop her, she'll be ok right?
