How to take increased stitches into a pattern

Happy Easter to all friends and knitters.
I am knitting a Baby sleeping bag and I am working the sleeves. I have seen the worrying words 'take increased stitches into the pattern and ‘keep continuity of pattern’. I have looked up ideas on Google and because I am working a 4 row pattern I have used stockinette for the increases at both ends of the row. Now I have finished the increases I have enough stitches to start the pattern again.
However should I have been able to take the increased stitches into the pattern earlier without having a section of stockinette at each side which looks a bit strange.
Here is my pattern which is from an old Baby pattern book.
1st Row.Right side.
K2, ,kyb sLIP, k5;. rep.from to last 3 sts ,
kyb sLIP, k2.
2nd row.
(Kyft sLIP, P1)twice, * K3,P1,kyft sLIP, P1; rep from * to last st, kyft sLIP.
3rd Row.
K5, * kyb sLIP, K5; rep from * to end.
4th Row.
P1, * K3, P1, kyft sLIP, P1; rep from * to last 4 sts, K3, P1.
I added 6 stitches on each end of the row by increasing 1 stitch at each end on the 9th row and every following 4th row going from 41 stitches to 53 stitches.
Please can you advise me. I do hope I have explained properly.
Thank you.

It’s neat to keep one stitch at the edge in stockinette stitch for simplicity in seaming. So one of the increases becomes this edge stitch. Otherwise, for a pattern like yours, you could write out an additional repeat at the beginning and end of row. Then as you increase stitches, work a partial repeat of the pattern as much as possible.
Stockinette or garter stitch is a reasonable alternative along the seam line here too.
Patty Lyons has a nice tutorial on keeping in pattern that might help.
