My DD is 6 weeks old this week and is taking more and more formula weekly, quite alarming really. She's taking 7oz of houngry baby milk every 4 hrs now!!! She's not being sicky so I presume I'm not overfeeding and she's putting on weight at a normal rate but I just can't believe how much milk she's taking. My friend's 6 month old doesn't take this much milk and never did before she started solids.
