He keeps waking up!

Sue

I feed my little one and then let him relax on my chest, sometimes he would fall asleep on me and sometimes I will take him to bed "drowsy but awake" either way he will fall asleep fine. it's just give it all about 10 minutes - 1 hour and he wakes up because he's dropped his dummy I will pop it back in and he will go back to sleep but it will happen again and again until he's in a deep enough sleep for him not to wake up for it or some how he keeps it in his mouth. I'm getting so frustrated 😤 and upset because he wants to sleep and I want him to sleep, and every thing I try don't work completely.....Unless I were to get him out and lay him on my chest again but I definitely don't want to get into a bad habit like that. Plus I can't sit around all day every day! What should I do?
