Haroula - I'm exactly the same as you. Amy is pretty much on full time formula now and it really varies the amount she takes every time. She's supposed to be on 180ml now (she's on S26 gold) but she rarely rarely finishes 120ml. I'm making up 180ml and putting 60ml aside so that if she doesn't finish the bottle I can keep that 60ml for the next feed and it doesn't get wasted. I took her to get weighed today and she'd only put on 90g in a week. She's never put on a lot of weight anyway but it just stressed me out so much. But I'm so over the weighings now. I mean, she was due for a feed and had done two big poos in the morning so if I had gone at 8.30am just after a feed and before the poos she probably would have weighed 200g more!!! So I'm not going to worry about weight anymore. She does seem very happy when she's not hungry, she's feeding every 4 hrs and she sleeps really well. I'm just starting to think that she doesn't have a huge appetite and has a fast metabolism so she will never be a fatty boomsticks. I have to tell myself that or else I'll go crazy with worry! her weight is now 4.5 kg. I'm going to go up to the next size teats (medium flow) and see if that makes a difference.....i don't really want to change formulas cos she's not getting constipated and likes it (to a degree anyway!). I hope things continue to improve for you xx
