Horrendous poos after transition to cows milk

DS has been the biggest grump for the past 3 weeks.... I was putting it down to learning to walk and teething but of course, there has also been the introduction of cows milk bottles instead of his usual formula as he turned 1 recently.

We introduced whole milk gradually and he did wonderfully transitioning, never refusing a bottle (he has one at breakfast and one before bed), but his nappies have been absolutely disgusting for the past 2 weeks since he has been having whole milk only instead of the mix.

I so don't want to jump to intolerance etc as I know it can take a while for the digestive system to get used to something new... but realistically... anyone have experience with this? His poo is very dark green and there is absolutely loads of it... blowouts when we haven't had any of those since he was 3 months old and we switched off SMA to Aptamil for the same reason... loose poops.
There is undigested food in almost every poo, but I think this can be normal too...? He also has started getting the worst nappy rash. For example, he was eating his dinner and did a poo... less than 5 minutes of sitting in it to finished dinner, I changed him and his bum was raw already!

He is gaining weight absolutely fine and has always been off the charts for height and weight.

Anyone have experience with this when switching to cows milk? Thanks!!

I should add, he sleeps well and doesn't seem uncomfortable during the day, which is why I hesitate at thinking intolerance. But he is definitely more grumpy than usual, the burning nappy rash and truely disgusting poo make me think twice. There have been no other changes to his diet while we did the milk transition. He has 3 meals a day and a snack in the afternoon. His appetite is and always has been very good.

Have left a message for HV but they've not got back to be yet.
