Struggling with my 8 month old

[Sawadee1234]

I need some advice and help. Not sure if this is topic is in the correct category but here goes.
My DD2 is one week off 8 months old. She was EBF for 6months befor switching to formula. She suffered from serious colic for the first 5/6months of her life and screamed almost constantly. A lot of bouncing and sshhing.. And using all sorts of remedies as it was trapped wind she suffered with. At 3months I assumed it would get better at 4months , then again at 5months thought it would get better at 6months and it did. To a degree.
We are using Dr Browns bottles as I was advised they are great for reducing colic. She has 3 'meals' a day. The problem is she suffers greatly from wind STILL. So much so that it is disrupting her naps (and it always has done to be fair) but I,m really struggling. Each time I try to put her down for a nap she screams and screams and screams. I have tried all tactics to get her to nap. Most times I give up as she is clearly not happy bout something.
Normally after getting her back up she burps about 5/10mins after n then will kind of go down easily. If she does manage to sleep she will only nap for approx 20 to 30 mins as she will always wake up screaming and then after about 10 mins burp. She is constantly over tired.
I have no time to do anything. My whole day centres around getting her to sleep as she's tired all the time. She often still has 4 naps a day and I.m really lucky if I get an hour out of her , but this is rare.
The nights are always ok but she's up n down a lot due to trapped wind in her tummy as I can hear it but can't get it out so I have to ssh her back to sleep. She then wakes at about 4 am n has about 2 pounces but takes 1 hour to go back to sleep as she cries with more wind. Last night was so bad she screamed so hard at around 5 am for 20 minutes. We use gripe water alot but it still is a problem. It isn't anything to do with solids as she has been like this from day one.
It's so tiring and so very worrying as I thought by this age they would outgrow it. Why does she swallow so much air even with so,ids too? And why does she suffer from it so badly? Anyone else had this or what should I do?? Apart from this she is meeting all her development early ish, crawling at 7months, sitting up at 5 months, pulling to standing at 7 months. She sleeps on her tummy too due to this issue from birth.
Any help appreciated.
