Mine is eating more..Remember how much they grow in the summer.. I am ensuring more milk, more protein, plenty of fruit but yes eating more..
Mine looks like he is a starved urchin at the mo so to be honest he can eat what he likes..It did a huge bowl of cereal this morning.. twice as much as I usually give him he ate the lot...
He is very active though.
not sure what your concern is
If it is finance...you are worried about, do things to make snacks cheaper, then do things like buy a block of cheece and cut it up into protions, buy a stack of yoghurts on offer, as others have said look at cheap snacks
If it is boredom, then get them some structure , it helps
If you are actually worried about weight look at healthy snacks and increasing protein.
I have wondered how come DS seems to need to much more but have no real concerns about his diet...Would he eat junk food all day if I let him...probably...But he knows how to eat properly..
