Oh mama, you are doing so well, two and a half weeks in and already so tuned in to your baby! What you're describing sounds like a classic comfort nursing phase, and many mums I know went through the exact same thing around this stage, it's actually really normal and even good for bonding and milk supply, so try not to stress too much about it. For the spit-ups, as long as he seems comfortable and is gaining weight, a little milk coming back up after a big feed is usually fine, but it's definitely worth mentioning to your PD just to be sure. One thing a friend of mine found helpful was learning to do the "twist and pull" unlatch, pressing baby's chin down gently or slipping a clean finger into the corner of his mouth to break the seal slowly, then waiting a little longer after he's in deep sleep (you'll notice the sucking slows right down and his arms go limp) before attempting the transfer. Every baby is different though, so some mums find this phase passes on its own in a week or two, while others do prefer introducing a pacifier more consistently to help, just keep trying and see what works for your little one! Do check with your doctor or a lactation consultant too, especially about the spit-ups and sleep, just to get professional eyes on it. You've got this!
