Nervous about sleep training

Hubby and I will be starting sleep training with our 6 month old this Friday. We are going through sleepwise and the woman we are working with is so sweet. It’s kind of like Ferber method but you alternate between verbal and physical touch. Anyway I started crying because I’m so nervous that when my little one is crying he’s going to be thinking “mommy why don’t you just pick me up.” 🥺 I know this will benefit him in the long run, but we were separated after he was born for 2 days because of covid rules (I was still testing positive 75 days after initial onset) so I’ve grown to want to keep him as close to me as possible.
