Hi, I really need some advice please as I'm not doing well on my own 
DD2 is 7mo but developmentally more like 4mo due to hospitalisation/sedation as a newborn. She doesn't hold her head up yet, for example, or turn over. She's growing well and a very long baby. She has/had reflux and dairy intolerance so she's on some drugs for that plus on Neocate with infant Gaviscon in.
The Neocate just doesn't do it for her and she is constantly hungry having a bottle about every 3 hours through the day. I've tried adding a scoop of Aptamil with a view to increasing it and getting her on normal formula but she comes out with a spotty face when I do this so I have stopped.
She was going to bed at 7pm and sleeping til 1.30am, then a bottle and sleeping til 6.30 (she's not yet slept through the night). However she's now waking at 11.30pm and then again at about 4am.
I'm very keen to get her weaned but it's going terribly. I puréed my own stuff for her but she wouldn't accept it, so I tried very runny Hipp purees which she accepts but they give her awful stomach cramps and trapped wind. They don't seem to make any difference at all to how hungry or satisfied she is - she still wants the bottles. I want to move her to lumpier stuff as I don't want to end up with a child who won't accept lumps but she won't even have the coarser Hipp stuff and just spits it out.
I try to get 2 solid feeds into her a day but I find it hard fitting in around the bottles and sleep and I've no idea whether I should space everything out evenly or what? Even when I give her a solid feed later on in the day (which I try to avoid due to the pain it seems to cause her) it doesn't make her sleep longer. What am I doing wrong?
With DD1 I did BLW which went really well and I would like to do this with DD2 but I don't know when she's ready for it as her hand/eye coordination is poor and she has severe visual impairment. Can anyone advise me on this?
She starts childminders in 2 months so I'm running out of time and we are so all over the place with no routine.
This is such a mish mash of different issues but I would appreciate anyone who can offer me suggestions, thank you
