Yesterday my MIL took my 21 month old out for the day and specifically asked for him to be wearing “beach appropriate clothes” we live in Scotland and it wasn’t sunny or warm at all when I was getting him ready so I put lightweight leggings and a T-shirt on him and popped a jacket under his pram incase it got any colder. I put sun cream on him and told her the cream was in his bag and would need to be reapplied later if he was getting out of his pram and she agreed. 3 hours later we get him back and he’s very sunburned. I asked about how it was possible when he had factor 50 on and she replied “I don’t believe in suncream as I’ve heard it can cause cancer, so I never put anymore on him ” my partner says I’m being unreasonable for being very annoyed as now my baby is sunburned, uncomfortable and I feel that is very irresponsible.
