I feel like a shit mom 😅

My son is 2 months old and I noticed he doesn’t coo or even really smile. I noticed earlier today that his ear had a black spot so I like used my nail to get it off and noticed wax so I looked inside his ear.. and wow. The amount of wax he had.. I don’t use qtips to clean his ears so I bought a tool that scraps the wax out and used it for the first time and got a lot of wax out. I put him in his swing and normally he cries but he didn’t this time. I let him swing for awhile picked him up when he started getting fussy and I started talking to him and he smiled at me! So I’m guessing the wax wouldn’t allow him to hear so I’m hoping he starts cooing soon now that he’s clean. I feel like crap for not using that thing sooner. I didn’t realize wax could build up that fast in a newborn/infant
