OK on item #3-biking.... "stabilizers" or "training wheels" on kids bikes are items from SATAN HIMSELF!!! (I'm an avid biker, and have raised 3 girls and taught them all to ride - the easy way - one is even special needs)....
anyway - here is how you teach a kid to ride. well they actually teach themselves! It's quite logical.... it works - tell others!
1) REMOVE and THROW AWAY training wheels, stabilizers, or whatever you call them. commit to NEVER using them!
2) Remove pedals - yet keep them... you'll put them back on soon enough.
3) Drop the saddle (seat) all the way down. so the kid can sit on the saddle (seat) and their feet rest on the ground so they can 'scoot'.
4) have the kid simply 'scoot' themselves up and down the sidewalk, lane, road, highway, freeway or whatever. think of the bike as a 'sit down scooter'.... pretty soon, they will simply 'figure out' weaving, turning, (balance) etc - with the saddle (seat) down, they can simply put their feet down for stabilization - yet will pick them up for longer runs.
5) when they get comfy by weaving and turning (note- learned ALL BY THEMSELVES ) then it's time to put the pedals back on - leave the seat (saddle) down low - you can raise it later.
6) since they've mastered turning and weaving - it's simple to pedal and go... they may be a little 'wiggly' - but they will get it in a couple of hours....
I've done this with 3 of my girls - worked with each one - and other kids whom I know... works every single time....
TELL other parents about this - it works and works well!
have fun!
