I have a tip about the breast pump. I nursed both of my daughters for a year and worked after they were 3 months old. I pumped at work twice a day every single day and managed to never have to give my 2nd daughter formula.
The pump I used was not electric but it was wonderful! It’s the Avent Isis pump. It costs around $40-$50, MUCH cheaper than the $200-$300 electric pumps.
I was able to get anywhere from 4-10 ounces of milk everytime I pumped (that’s alot for pumping!) and the reason was the “massaging petals” on the pump, it feels like a baby eating so the milk lets down easier and you get more milk. It was a wonderful investment and considering the number of times I used it, very well made!
Let me know if you need more info about it and I will try to help.
