Re: New here and have a couple questions!
Are you sure that you don't want to try nursing? Your daughter is still so young that it could be possible. As you know from last time, exclusive pumping may be easy to do in the short term, and really, I don't think it's easier than nursing, but anyway - it's going to be much harder for you this time with a 3 year old running around as well. And also, what are your breastfeeding goals? When you stopped pumping at 5 months last time, was it because you were sick of pumping? Or because you had reached your goal?
I'm only asking those questions because I pumped at work for both of my children for their first year and really hated the pumping. But I love nursing them. It's actually a relief to me to NOT worry about how many ounces are needed for a bottle - my baby can just nurse when I'm with her and she'll have however much she needs. And I don't have to worry about taking bottles out and about and keeping it cold, etc.
To answer your questions - I think your milk will be fine in your fridge freezer for at least 3 months. But if you're really going to EP, you should probably get a single dedicated freezer. It sounds like you have an oversupply right now so you'll want to take advantage of that. Also, I don't know why it wouldn't be safe to give your daughter chilled milk. It should be fine. It doesn't need to be room temperature or warmer, it's just nicer (in my opinion).
