Ive had this problem too- given that all the other babies at MG still not mobile, but Izzy is crawling and is a force to be reakoned with! No toy or child is safe and other bubs are reaching out and grabbing others toys too. We have discussed that we all need to be prepared for them to share toys and drool. We also trust that if our bub hasn't been well, we won't go to MG that week, and we all take toys that can be easily washed when we get home too. One mum is a bit precious about it all, but really, there isn't much we can do about it! I would maybe have a general chat about it next time you meet! Good luck!
