Hi Louismummy, I was also intending to bf until 6 months but DD didn't seem to be getting enough either and started waking up 2ce a night for feeds (I know, nothing compared to 4 times, but feels like a lot when she's only ever woken up once) and being quite desperate for food during the day. Didn't really ever seem to have enough milk for her.
Anyway, started on baby rice 2 weeks ago and she's loving it, now on 2 baby rice meals a day (did try 1 meal a day of organic baby porridge with banana but she hated that, and she's come out in a funny rash from the organic mash potatoes and rosemary that I tried) and can't seem to get enough. She's sleeping much better, is getting enough food to actually NAP during the day (previously unheard of - she's almost always been awake 7am - 7pm, probably due to feeding so much / being so hungry) and is absolutely loving it. She's even fighting us for the spoon coz she wants to feed herself!
According to Annabel Karmel all babies screw up their faces at their first meals, but it's just coz it's a new taste / experience, so don't worry too much about that.
Don't beat yourself up about not bf solely for the 1st 6 months, if Oliver's hungry, feed him! Babies decide when they're ready and all develop at different paces, 6 months is just a guideline. We don't expect all babies to try standing / crawling / walking at the same time, or expect them to have teeth by a certain age, why do we have to be so strict about first foods? people used to be told the best time to start babies on 1st foods was 3 months, now we would be hung in the streets!
I'm sure Oliver will be fine, and will be gobbling up his baby rice with glee in no time!
Re more milk, I tried Fenugreek but found it didn't work for me personally (although a friend of mine has almost immediate results!). I find that a pint of Guinness in the evenings (when I won't have to bf for a good while) and some dark chocolate boost my milk production quite a lot. Don't know why it works but I do know that if I change the formula the next day I have much less milk, so am definitely sticking to it!
Sorry such a long post!
