For anyone who read the "I want to give up" thread, I've got a bit more news but the other thread's already so long I thought I'd start a new one.
DD was last weighed on 24/7 and then she was weighed again today and she'd put on 1lb!!!! I couldn't believe it! Now she's past her birthweight (finally!!), with an extra 10oz added on!! I can't believe it took 6 weeks to get back to her birthweight but at least we've done it now!
I still wish I could have got the breastfeeding sorted but I did that almost exclusively for 4 weeks and she just kept losing weight, so I'm just glad she's feeding well now and putting on weight properly.
Anyone who kept up with the old thread knows how stressed I was getting with it all but now I've switched to formula I'm unbeliveably relaxed and dd's growing like god knows what! And she seems happy and content now, which is nice!
Not trying to do an advert for formula - if I could have achieved this with bf'ing I would have but dd had a bad start and it just wasn't to be. Now I realise that as long as your baby's happy, it doesn't matter what's officially best.
So thanks to everyone who gave me advice and stopped me going loopy through it all. Now I can wait for dd to turn me slowly loopy like every other parent!!
