It’s that time of our life again…… potty training! With us finally owning a car and in need of car seats it suddenly dawned we could end up washing it a lot. Our seat as you might be able to see has a layer you can remove and wash but it’s threaded through the straps and requires taking the seat out of the car and unfastening the 5 point harness straps to remove. An extra layer with waterproofing was needed.
First off you need to measure the following.
Red: between waist straps
White: from back (or where you want edge of mat to start) to crotch strap
Green: measurement between edge of seat area to crotch strap
Purple: from straps to where seat area ends (where knees start to bend)
Yellow: if you want your mat to go slightly up the child’s back then measure higher. out seat is slightly narrower on back than were bum sits.
Pink: full length of mat
Blue: crotch strap to seat end area
You will also need to measure width of crotch strap.
I took off the crotch strap cover to draw around.
I wanted a mat that I didn’t sew then turn out and topstitch because if you use fleece like I have it creates bulk! So I sewed it without turning. This means you don’t need the same seam allowances as you normally would. I added 1 cm to edges to give me some room to trim them. If your confident with not trimming then add nothing.
As you can see from my mat the top is slimmer and widens out to cover leg area. To save making holes for the strap clips I cut up the middle and created a small triangle to fit the strap. (see below for a coloured line picture to correspond to seat measurements)
You need to cut two from fleece of the mat and the crotch strap cover. Lay the fleece with one layer wrong side facing up, overlap waterproof material (I used clear PVC) then the second fleece layer right side facing up. Sew around the edge and trim the waterproof fabric away neatening edges.
Lay the two crotch strap pieces wrong sides together and sew round outside.
After you have sewn the main mat and crotch strap piece lay it central to the triangle (this represents where the strap goes) Sew into place so the crotch strap piece covers the gap.
Crotch strap piece lifted up and laid down. When in use it will lay on top of clip and protect it.
Now put in place and fingers crossed it’s not needed!
I used fleece and clear PVC as fleece wicks away moisture but doesn’t absorb it and leak it back out so it doesn’t stay wet!
Other alternatives are suede cloth with absorbent layer under like terry towelling.
You can use ripstop, PUL or an extra layer of fleece for the waterproofing. It all depends on how long you plan to use it, your child’s needs and how heavily they may wet. Pul is breathable and machine washable, extra fleece will wick away moisture well but if your child is a heavy wetter it will seep through so is only useful for little leaks or you will need to layer up with more absorbent fabrics.. Ripstop comes in different thicknesses, or weights, and the thinner stuff that usually is plan is more machine sturdy than thicker patterned stuff. All these fabric also dry fast which is perfect.
PVC can’t generally be machine washed so I will need to hand wash but when my son has an accident it’s usually very little therefore I don’t anticipate needing to wash much.
