Na, don't think it's a bad thing

My dd was high maintenace too, so I hear you on doing what he needs to go to sleep. There were a time when she only slept ON me. Then when she only slept while rocking. You do what you can. DD is now 15 months and goes to bed at 7pm with a bottle and when I check after about 15 minutes, she is sound asleep and did not even make a sound Just commented to DH last night about how easy it has become

So do what you feel is right, later his needs will change and you have to adapt. If rocking/patting/sucking your finger gets him to have the rest he needs .... it's never a bad thing. LATER when his reflux is under control and he is a bit "better behaved" you can start by putting him to bed JUST before he falls asleep and start weaning him off your finger, so to speak. But that's later. DD started going to bed on her own around 8 months or so.

You are doing a great job!!
