Sleep training worsen separation anxiety?

I’m on night 4 of sleep training my 9 ½ month baby. I understand this is around the same age separation anxiety kicks in but has anyone experienced sleep training making separation anxiety 100x worse during the day?? Before sleep training, my baby was very independent and would play by himself for pretty long periods of time, enjoyed playing in the water, going on walks in the stroller, etc. But as soon as sleep training started, he will NOT leave me alone during the day. I have to carry him 24/7 or else he’ll scream at the top of his lungs. Its not enough that I’m in the room. I have to be carrying him or he has to be cuddling me. It’s sweet but its also really exhausting.

Did anyone experience anything similar and is there anything I can do to ease his anxiety during the day?

Thank you
