Hi Lyndyloo
I have a very similar problem, my DD is nearly 6 months and started nursery this week. She can?t have formula because the few times I have tried it, it has made her very ill (lots of vomiting), and now she won?t drink it anyway.
She?s quite a small baby (12lbs 7 at 25 weeks), and if she has an EBM feed she will only take 4oz at one feed. She usually has about 7 feeds a day (including night time waking ones).
Our current routine is that I feed her before we leave for nursery (about 8.30am), she has baby rice watered down with stewed apple juice mid morning, I go back the nursery for a quick bf at lunchtime, she has a 4oz bottle of EBM in the afternoon (and more baby rice if she will take it) and I bf all evening and during the night. I?ve got a bit of stock in the freezer, but also find it difficult to express much, usually only manage about 2-3oz a day, so am worried about keeping supplies up.
I haven?t tried expressing at work - although this is obviously a good solution if you can manage it. (There isn?t really a suitable room to do it in where I am, and I can?t usually get a let down without DD on the other boob.)
One thought I had was that baby rice (or whatever solids she is taking) watered down with made-up formula might work for you, maybe mixed with some apple juice to disguise the taste or something?
I have found that the nursery are very good at recording exactly how much (including milk volume) she eats and drinks and when, so although it may take a few days, you should get a good idea of whether any EBM is being wasted and adjust accordingly.
Sorry this is a bit woffly, but good luck and hope your DD settles well
