DS aged 4 woke up with a sore foot today - couldn't put it on the ground. He's had this twice before, both the day after being on the beach and running on hard sand - that's what I put it down to anyway. That's not the case this time - yesterday was a normal day, no beach in sight... It's usually ok by the end of the day. Today it's fine now! Have a GP appt at 3. Would you take him or not?? has anyone else had this with their LOs?
