So my LO is 5.2 months and lately he wakes up ravenous! Like every 2-3 hours he wakes up starving, I can actually hear his belly rumble. He's formula fed, I haven't started him on any kind of food. Formula only at this point. Is he maybe going through a growth spurt at this age? Or maybe just very hungry now that he's getting to be a big boy now? I'd rather not start him on anything food wise until he is actually 6 months. So I can tough out being woken this often (used to it now lol) but when he is 6 months, what do I feed him that keeps him full at night? I'd rather not give cereal.
