Babysitting for our 5 month old while on holiday!

Hello ! My husband and I are on holiday in Switzerland this week and we would love to do a canyoning excursion together but we would need someone to watch our 5 month old baby for 3 hours while we’re gone! We would meet up with you in interlaken and have you walk him around in a stroller or sit at a cafe or somewhere in the shade for the 3 hours while we’re doing the activity then meet back up with you to get him afterwards
