Is anyone on Gv adhering to the feeding regime? We were eating on demand, but for this week I started feeding every 1.30-2 hours. We've been doing it for a month and 3 weeks. Do you think it's too early? If we feed on demand he would snack often, because of that milk remained and there was a lactose blockage ?‍♀️ Now he eats straight well? But if we feed by time then the increases will be small, right? In one month we added 1.5 kg. Now it's at 1 kg and the weight increase is due to the regime ?‍♀️
