This might sound really silly but I'm a first time Mum and need some advice.

Madeleine is almost 10 weeks old.

She is already holding her head up really well. She is also giggling and trying to stand up on me when I'm trying to burp her. She's really strong! She also holds her dummy and has been putting it in and out of her mouth.

Is she still a little young? I thought they had to be AT LEAST 12 weeks to do these things.

Did anyone else experience this?
