My dr said I could start this at 4 month and just once a day. It made him constipated so a friend said she put fruit so far I’ve just used peaches. Ive only been giving him 2oz every night bc that’s what the container says. Is it okay to go to 4oz the container doesn’t say anything about it so I wasn’t sure? And another question once you e opened a jar of baby food can you put it in the fridge and save it for another time if so how long will it keep in there? 

He is now 5 months!
