Ari's milestones

Ari is now pulling himself up to stand up more and more. I knew he was thinking about standing up even before he did it the first time. It is almost too easy to read his thoughts, or perhaps it is because I am a parent for the second time around.
After rolling over at 2.5months he has not looked back. He was sitting with support at 5.5, unsupported at 6 months, crawling at 6 and at 6.5 is already standing holding on.
His personality is completely different from Nidhi's. He is not into books, except for chewing the pages. He will not stay where you put him down. He will go into another room leaving you behind. He will crawl under and behind furniture. He is already thinking about opening cupboards even though he cannot do it yet.
He loves his food and is eager to eat whatever we are eating. He wants a variety. He is not too keen on breastmilk and I think he may be weaned much earlier than Nidhi.
He isn't making a lot of sounds. At this age Nidhi was already making consonant-vowel combinations like ba-ba sounds, but then she was early with her verbal skills. Plus Ari is being subjected to Malayalam and English while Nidhi just learnt the latter.
