My daughter is 3 months old exactly, weighs 13 lbs 3 oz. She has 2-3 poop diapers per day and seems to pee plenty. Her weight gain was good at her 2 month checkup--she was in the 90th percentile at birth and had fallen to the 75th at 2 months but her Dr. was fine with that. In the last month she gained just under a pound, so she's lost several more percentile points, which I think is still probably OK but I'm a little concerned about the trend and I don't want her weight gain to decelerate any more.
I went back to work a couple of weeks ago, but even in the week or two before that, I was really starting to notice that my milk supply is dramatically higher in the morning and wanes over the course of the day. I'm mostly going by the swallowing I hear baby doing when she nurses and how full my breasts feel. In the morning, my breasts always feel full and baby takes huge gulping swallows. In the evening she never seems satisfied despite feeding almost constantly, my breasts feel deflated and when she does seem to be getting milk, it's an occasional swallow after a lot of sucking.
I pump at work in the morning and afternoon and see baby at lunch to nurse. I leave the milk I pump generally for the next day. I have a freezer stash but I've never dipped into it (I make a deposit on Friday and a withdrawl on Monday in order to rotate it but I run at a surplus.) During the week, I always pump a few oz more than baby takes. On the weekends, I will sometimes pump in the morning because my breasts feel very full even after she has nursed once or twice. The result is that I always have a few oz of extra milk in the fridge that come from my very ample morning milk supply. She is taking 2-3 bottles during the work day, usually about 3.5 oz each (depending on how well she nurses at lunch). I will pump 6-8 oz in the morning and maybe 3-4 oz in the afternoon.
In the evenings though, she always seems hungry. I have resorted to giving her 2 oz of pumped milk a couple of times, which she gulps down. Is this a slippery slope? I know that a bottle of formula at times like this can be counterproductive but what about milk I pumped earlier that day? I worry because we're already giving bottles during the day, and I know that going back to work and pumping can sometimes result in a drop in supply. So I don't want to amplify the problem by giving bottles in the evening. Also, I would obviously rather nurse in the evenings.
Should we avoid giving her pumped milk in the evenings? What can I do to increase my supply in the evenings? If I just keep nursing her constantly in the evenings, will my supply eventually respond? Should my husband (who is with her during the day) try to offer her the bottle more often so that she isn't as hungry in the evenings?
Feeling a little out of whack here! Thanks for any help.
