This is my third day back at work and I'm worried that I'm not able to meet DD's needs. She will be 11 weeks old tomorrow, is exclusively breastfed since birth, and is gaining weight well. Last Friday she was 10 lbs 4 ounces at her 2 month well baby checkup. We have a freezer stash of approx. 100 ounces. I'm able to pump 3 times a day at work with an actual pumping time of 15 minutes at each session. I simply can't be away from my desk more or I will have to work longer to make up for it (I'm salaried/exempt).
I nurse her at 6:30 AM and drop off at daycare at 7:15 AM. I'm at work until 4:15ish and pick her up 5 minutes after I leave work. By the time we get home it's after 4:30 so she's going roughly 10 hours between nursing sessions. She will nurse at around 5 PM and again at 7 before she goes to bed, then I get her up at 10 PM to nurse before I go to sleep, and she eats at least once between 10 PM and 6 AM. Adding in the three bottles at daycare, she's feeding an absolute minimum of 7 times a day and usually it's 8.
On the Kellymom milk calculator if I put in 7 feedings/day that works out to about 3.6 ounces on average per feeding (high of 4.3 ounces), and if I put in 8 feedings/day it works out to 3.125 ounces (high of 3.75 ounces). For three bottles that ranges from 9-13 ounces that I need to pump. My LC says to start with the 1 ounce/hour rule, which implies I need around 10 ounces minimum for the time we're apart. I've read on here a 1.5 ounce/hour guideline, which means a max of 15 ounces? Yikes.
DD will suck down whatever she's given in a bottle, whether it's 2 ounces or 4 ounces - she has never not finished a bottle. The first day I sent 3.5 ounce bottles but yesterday and today I sent 4 ounce bottles. Monday and Tuesday I was able to pick her up at 1 PM so she only needed 2 bottles between 7:15 and 1 PM. Based on when the took her bottles she will likely want to eat again at around 2-2:30 PM. Her daycare providers won't offer a bottle after 3:30 PM at my request so that she will want to nurse around the time we get home.
Yesterday I managed to pump exactly 12 ounces in three sessions, so today I sent three 4 ounce bottles. I feel like I "should" send at least three 3.5 ounce bottles at a minimum (10.5 ounces total). I think I can probably get the 10.5 ounces or so but I worry about being able to get 12+ ounces every day.
Today I've pumped once and only got 4 ounces. Since my pump yield decreases as the day progresses I am worried I won't be able to pump enough to send 12 ounces to daycare tomorrow. If I have to, I'll pump after she nurses at home to get the rest of what I need rather than dip into the freezer stash.
How do I work out how much milk DD truly needs while at daycare? I need a target to shoot for here. Worst case scenario do I send 3.5 ounce bottles and see if she's still OK with getting slightly less milk once she's actually in daycare a full day?
I don't know if I should start taking fenugreek or resorting to other methods of increasing supply or if I should wait a week or two to see if things improve as I get acclimated to being back at work. Any thoughts? I do have the freezer stash as a buffer but I don't want to touch it unless I have to, so for now I'm thinking if I need to pump more to get three 3.5 ounce bottles, then I will do that rather than using stash.
