Hi, my DH has been home with our 4 mo daughter while I am at work for a little over a month now. They come to see me at work for lunch and I nurse her then but they have never gone on an outing that required packing bottles of EBM and we are both confused. At home he takes a bottle from the fridge and warms it in hot water. Can anyone share what they would do while out for say, 3 hours with EBM bottles? Does he bring the bottles on ice packs? How to warm it? I am not sure if she would or should take it chilled. And how much to bring? If he feeds her right before he leaves the house, he will want to bring a bottle just in case but it might not get eaten. What then? Just feed it at the next deeding? She doesn't take fixed amounts at fixed times, so she is not that predictable. Thanks!!
