Derlor/Daisy...
After my post this morning Re SMA white, (before I read your responses) I did do a bit of research and found a thread on MN pretty much echoing your comments. I agree, it's not the right thing for him, my mum suggested it but I don't think it's the way forward.
I decided to keep him on SMA Gold as generally he is good on it, but sometimes we get days where he is taking 1oz every hour one minute, then 6oz every 2 hours, and he has been very fretful and screamy and unhappy, and all up it has resulted in me, DH and LO being depressed and tired and me more often than not me weeping and wishing I was the other side of the world.
However... I am going to keep some emergency cartons of SMA white on the side for those nights when he is impossible and I am crying. I feel human again, I don't hate him, (sorry peeps, but yes when I am that tired I actually regret having him and keep calling my mum begging her to take him off me) and tbh I think it is better that I have an emergency solution and a happy mum.
On another note, he is much happier himself today. He has been back on Gold this morning, he is smiley and chirpy, feeding well and settling. I think he needed the rest as much as I did.
I do want to do what is better for him, and so I am going to keep him on the Gold - but also I need to look after me too, and if giving him a carton of the heavy duty stuff of an occasional stressful evening means that I can face another day as a parent, then I'll do it!
