My baby is 5 mth now and I want to join back for work. Am I being selfish , should I wait till he is 1 or 2 yrs?

Hey, No, you are not at all being selfish. Having a baby doesn't mean that you have to compromise on your dreams and aspirations. It means adding upto what you already have and not otherwise. I think if you have a good support structure or have a good nanny or daycare to look after the kid when you are out then you can go ahead with a happy face. Also, should you wait for some more time or not is entirely your call. But deferring it thinking that you are being selfish is completely wrong. All you have to be is sure about yourself that are your ready? Because, I hope you know that whenever you join back, you will too go through separation anxiety along with the baby and there will be several teething problems and you should be mentally ready to face them head on. Having said that, this challenging situation is not something that only you would go through, all mothers go through this, so not to worry, you will come successful out of it. But, all you have to make sure is that are you mentally and physically ready to get back to work. If yes, then, please go ahead. Good luck! :)
