Congratulations dear. I have also a 4year baby named zaid. I had also experienced the moment you are enjoying. I would like to share some valuable experience I got as first time parents and would advise few valuable tips. Please try to breastfeed the little one as much as possible. For extra breast milk the mother can take ayurvedic medicine like lactare. I would also suggest to install parenting apps like baby centre or indiaparenting on your phone to get daily tips for your little one. The new parents don't know the daily changes in little one's life so this app will be very helpful.
