Hi,
Probably massively overreacting but took my 4 month old out at the weekend. Kept her in the shade, had a parasol etc. However sometimes her little leg was exposed whilst walking in her stroller (a few seconds at a time). I put a thin Muslin cloth to cover her legs but she kept booting it off so I reckon she was exposed a couple of minutes in total. Then when I went to the car, my husband gave her to his friend but he must of been in the direct sunlight for 5 minutes. Will she be ok, she isn't sunburnt or anything. She had a sunhat on too. I know they say not to expose to direct sunlight but sometimes in the stroller its impossible to stay in the shade all the time. I need to get my lil boy from school too.
