6.5 month old 14.11 pounds

I am not sure if it healthy or not but i dont know what else i can do to put weight on him. I have started him on solids such as some fruit veggie purees also some chiken soup puree.He eats formula hallo it a german brand. He eats before he sleeps each time rarely while he plays. So he would eat around 8-10 ounces before bed in amiddle of the night he would eat around 6 ounces once. Then he wakes up i try to feed him but he wont eat until his first nap around 9 which is around 7 ounces then 1:30 another 7 ounces and maybe cluster feed until bedtime about 3 - 5 ounces. And 6 30 goes his 10 ounces. .... I bought him some cookies he likes also some oatmeal please help who can relate

My husband said his weight is fine. I am not sure what to do.
