6 month old still not sleeping well.

My son is just about 6 months old and we are still struggling with consistent sleep at night. He fights going to bed every night and wakes up roughly ever 2 hours for about 10 minutes. During that time my wife will feed him and he instantly falls back asleep. He barely eats during that time it is more of a just comfort thing and he falls back asleep on her.He currently takes 2-3 naps a day ranging from 45 minutes to about 1.5 hours at a time. The total sleep time is about 12 hours at night. We usually start the going to sleep process around 7pm. What are we doing wrong?Are the naps too long? Do we need to be tougher and just let him complain in the crib at night?My wife and I are starting to get frustrated. What are some suggestions? Thanks via /r/Parenting https://ift.tt/3jjYS8o
