My LO is 14.5 weeks old, she was born one ounce away from albs and now weighs about 13.5lbs. She's been 100% breast fed and has been gaining weight and growing at a good rate.
In preparation of my return to work next week, we have been giving her at least one bottle of expressed milk a day. We offered 4oz and she'd usually leave one to one and a half ounces. This past week she started sleeping anywhere from 8 to 10 hours without waking at night but continued to eat every three hours. Since then she would finish the 4oz and keep sucking for more so I offered her a half more and another half more and she kept taking it. Due to different reasons this past week (family emergency keeping me away from her, medical procedures inhibiting me to nurse her) she's been receiving more and more bottles of expressed milk while I pump and she's now up to 5.5oz at a time and drinks about four times a day.
I pump as much as 8.5oz in the morning and from there my supply dwindles to 4 and then 3.5 and then 3 and then as little as 1.5oz. Sometimes I make enough in total for the day that she drinks and sometimes I don't and when I do it's because the morning pump session extra ounces helps. The other night I nursed her for bedtime and she wouldn't sleep. She stayed a little fussy so I offered her a bottle and she drank it all!
I haven't had to supplement with formula yet because I've been digging in to my freezer stash and the excess I pumped in the mornings.
I realize that pumps aren't as good at removing milk as your baby but I can't help but worry that she isn't getting enough from me anymore. She'll need about three bottles for her caretaker when I return to work in two days and I know I won't produce the 16+ ounces in those three pump sessions during the work day to make up for what she's drinking. And then I get home and want to nurse her but I've only been pumping about 2 ounces around bedtime. She's been sleeping so much more during the night and wants five ounces at a time during the day and I don't produce that much in three hours, let alone at the end of the day before she sleeps.
I'm at a loss. I know that formula isn't evil and its okay to supplement if I need to but I'm afraid this is the beginning of the end and I really wanted to nurse her for longer.
Because of my work schedule and her sleep schedule, I'll be nursing her once before work, she'll have three bottles while I'm at work and then she'll nurse when I get home before bedtime. If I need to supplement due to my low supply at the end of the day I will only nurse her once a day. Do I nurse her and then offer her formula before bed?
