Good baby advise

When I had my first baby everybody had great advise for me.
Because I didn't know anything about babies I had never changed a nappy and only had held two babies before Lena was born I listened to it all and everybody had their opinion.
So many people give advise about what to do with the baby and how to do things with the baby.
the first 6 weeks I did everything that people advised me to do It was only after the 6 weeks that I started to get to know Lena and what to do.
The advise is all meant really well but it stays advise, I always say advise needs to be made your own.
Now Lena is three months old I know her and what she wants and what works. Now I can prove all those know it all''s wrong. Every baby is different and the person who is with the baby 24/7 knows the baby best.
I am following my own instinct now and when somebody gives advise I take it as advise make it my own or let it go in the one ear and out the other. As a first time mam and never interested in babies I found it all very confusing but together  (Lena and me) we are getting there
