Hi guys! I’m graduating next week and will be taking my 9 week old baby who is exclusively breastfed. During the ceremony I will be seated away from the guests and so will be leaving him sat with his daddy and my mum for an hour or so, therefore won’t be able to feed him from the breast (also could be quite tricky in a dress and gown). So I was planning on bringing some EBM for him just incase he’s hungry during that time. The only issue is I will need to thaw it before I leave, we will be driving for about 30 mins or so and will be arriving around an hour before the ceremony. My question is - how long would the EBM be able to sit in an insulated bag, such as the Tommee Tippee ones, before needing to be discarded? Any advice would be appreciated!
