Hello, really sorry if this wastes your time. I called 111 but they referred me to the NHS website but I couldn't find anything. My mum has stage 4 breast cancer. She's been on chemotherapy tablets for the last couple months. Yesterday was the first day shes felt well enough to visit. I asked her if she wanted to feed my baby as I know she feels like shes missing  out on her first grandchild. I went to the loo come out and she told me she used her tongue to measure the temperature of the food and then fed it to him. I wasn't gone long so it would of been one or two spoonfuls. Is this something to worry about? Can the chemicals be transferred via salvia? He spit up abit yesterday and slept in late but otherwise fine.
