Eating Solids

Has any of you given the go signal to start solids earlier than 4 months?? I have read multiple articles that if the baby's weight is doubled from birth weight or if they weigh about 13lbs that it may be a sign that they are ready for solids..

When I saw the 13lbs I was like what the heck...My LO is only 7 weeks old and already weighs a little over 13lbs. He was born 10.2 though..

I know a couple friends that got the go signal around 4 months and have a feeling that might be my case once we hit that mark. Just wondering if any of you started solids early too 😀
