Hi Fiona - Welcome (again) to the forum! You will find loads of information here about everything you need to ensure that Bonkers leads a happy, healthy life.
Feel free to post any questions you feel need answering (no matter how silly you feel they are, because I can assure you I've probably asked them before)!
Bonkers will still be very friendly towards anything and anyone - they really aren't too independent at 15 weeks.
Get the camera out and post some pictures - I love babies!!!
