The safest place for your child in any vehicle is in the back seat.  The center of the rear seat is preferable to outboard positions, as long as you can achieve a tight installation, because it is the furthest from a side impact.

Infant Carrier
Restraints manufactured to AS/NZS1754-2004 - When your child's shoulders are level with the top slot of their Infant Carrier it is time to move into a larger seat.
Restraints manufactured to AS/NZS1754-2010/2013 - When your child's shoulders reach the shoulder height marker to change to the next suitable restraint or forward facing mode.

Convertible Car Seat
Restraints manufactured to AS/NZS1754 - 2004 - Your child is too big for a Convertible Car Seat when their shoulders are 25mm above the top harness slot.
Restraints manufactured to AS/NZS1754 - 2010/2013  - When your child's shoulders reaches the shoulder height marker to change to the next suitable restraint or booster mode.

Booster Seat
Restraints manufactured to AS/NZS1754 - 2004 - If your child’s eyes are above the top of the Booster Seat back when seated, this is an indication to move to the next form of seat.
Restraints manufactured to AS/NZS1754 - 2010/2013  - When your child's shoulders reach the upper shoulder height marker to change to the next suitable restraint.

Booster Cushion
Restraints manufactured to AS/NZS1754 - 2004 - If using a Booster Cushion with no back (e.g. Nova) then the child’s eye level must be below the car seat back or headrest when the child is seated.  
The introduction of the AS/NZS1754 - 2010 saw the deletion of Booster Cushions due to their inability to provide side impact protection. Safe-n-Sound ceased manufacturing booster cushions in 2011.

Each child restraint seat has a flame retardant cover which can be removed for cleaning. Cleaning instructions are on the care label attached to the cover. All child restraint seat covers are machine washable (gentle cycle), cold water only, rinse well, dry on flat surface, do not tumble dry, bleach or dry-clean.

Good shorts but they run big
Size: 38, Color: Dusty Olive
I've been losing weight and picked these up in my new size (38). It turns out these are cut for a generous American midsection, and have an elastic fit in the waist, so you can (and probably should!) safely go down a size. I got mine in 34 instead and they fit great.

Great fit, functional, most comfortable shorts!
Size: 30, Color: Anthracite Camo
These are my go-to shorts, I now have five pair in different camo colors! I suggest one waist size smaller than you normally wear, (I buy a 30 instead of a 32, because they stretch and would be too sloppy if I purchased my regular size). The large open slotted pocket on the left, behind the Velcro flap pocket, is perfect for a normal sized cell phone. Plenty of utility pockets for EDC. Since these stretch slightly to accommodate movement and sitting, they are extremely comfortable. Also, my wife says they are good looking on me, so that gets an extra star!

The perfect throw-on athletic dress (with built-in shorts!)
Size: Small, Color: Navy Blue
I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day. The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky. The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference. I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is. Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!

Perfect for summer days.
Size: Medium, Color: Deep Gray, Size: Medium, Color: Deep Gray
I absolutely love this little athletic summer dress. I typically wear a size ten and ordered this in a medium and it's a perfect fit. I have the straps short so way it doesn't look baggy. It is super soft and comfortable. It is breathable and a perfect cut and length for me so so I plan on wearing it all during hot summer days. This is very versatile and easy to style by layering different things underneath it. I have a gray and leopard sports bra that is a really close shade of gray so it almost looks like it's one piece. I plan to order the teal as I have a swimsuit top that will match that color spot on. It seems like it is good quality and should hold up well to normal usage. I like that it has really big pockets , but I likely will not use them often lol. I just like the fact that if I need to have pockets they are there.
