6 Months old baby feeding issues. Okay?

Greetings It is normal for a 6-month-old male baby to weigh 6.2 kgs, as the typical range is 6.4 to 9.7 kgs. He is slightly below the average but still within a reasonable range, and steady growth is key. The milk quantity of 600-700 ml is also acceptable, as babies at this age typically drink 600-960 ml per day. The feeding aversion, where he only drinks milk when asleep, is a common behavioral issue which often results from pressure to feed or an underlying medical condition. This can be due to teething, ear infection, or reflux. Using a cup or spoon can help ensure hydration, but the root cause should be addressed. Regarding his inability to sit up well, this is also normal for his age; most babies sit with support at 4-6 months and independently around 7-9 months. He is developing appropriately, and you can encourage muscle development with more floor and tummy time.
