Let me tell you I tried. I tried with my son and I tried with my daughter. With my son I tried until he was 10 months old. Not as well as I should've or could've because I was a first time mom with little know how and it just didn't work for me. My son and daughter both refused or poorly latched on. When I saw a lactation consultant they miraculously latched on perfectly but at home nope, nada. They would cry, they would fuss, they would not eat. My son I understand, I didn't have my milk come in for about 2 1/2 days and so I had to supplement. After that I had to fool him, I would pop in his bottle, quickly remove it and then pop in my boob. Yeah it was annoying, frustrating but I felt guilty like you can't imagine. I did this practically every meal, except at night. Slowly I gave in and at night time I fed him only formula.
I wish I would've known or tried pumping sooner. I waited until I went back to work at around the 3rd or 4th month. I initially pumped 12 ounces, slowly it went down. By the 8th-9th month I was lucky if I got 2 ounces all day but I kept doing it until I quit at month ten.
With my daughter I tried for two weeks to breast feed but she had a hard time. Same thing with the consultant happened. Worst was that she cried and cried and woke up my other kiddo. I then had two kids crying a knocked out husband, he could sleep through an earthquake and a sleep deprived mom. This time around though I'd ordered a pump, free through my insurance and pumped every feeding to save my sanity. She got her breastmilk bottle, I got sleep and my son was happy to sleep too. I feel you kiddo lol. Going back to work I sacrificed my breaks for pumping sessions, woke up early for it too, slept late but it was easier than the 1 hour sessions that weren't enough for her and kept my toddler and me frazzled. My supply was good for about 5 months then it started going down and my stash went with it.
