Then it dawned on me while reading this, that another mom out there whose kid is probably 2 years old or more and can't say a sentence will start feeling bad and wonder if something is wrong with him/her. Please and please don't feed into that B***S***, hardly will you find a 6 months old that can form a sentence with 4 words. I personally have never seen one baby that does that. Don't judge yourself or judge your kids based on someone else's achievement, kids are different and they grow up in their own unique way.
My first son didn't say much until he was 3 years old, a lot of people showed concern and even guess maybe something was wrong. I felt a bit pressured at one point, so I took him to see a speech pathologist. I was told nothing was wrong with him, he was just having a speech delay, which I was told was common in boys, especially firstborns. I know better now, not to be pressured by the opinion of others when it comes to my kids unless a specialist detects something wrong. My son is 5 years old now and talks too much, he is very inquisitive and always trying to bring up conversations on his own.
The bottom line is, don't compare your kid in all aspect of life to that of someone else's kid. Your kid will grow on his/her own and with proper guidance become better. If you have kids having challenges or difficulties, be it speech or something else, don't be pressured to believe something is wrong. Kids are wired differently, you need to support your kid, help them succeed and build a better version of themselves.
