Hi E.,
Your instint is correct with wanting to stop the pattern that's starting.
My first born (boy) always nursed in bed and we co-slept. When baby number two came around it was so hard/devasting for my son to learn how to sleep on his own, in his own room. I always felt bad; like I did that to him by not being more responsible early on and taking the easy route. I think it's so important for babies to sleep in there cribs in their own room. They need to learn how to self sooth and feel safe without always needing the comfort of mom or dad.
With babies number 2 and 3, they went right into their crib the first night, I nursed in their rooms, and back into their crib and they are my BEST sleepers.
Try to create a tranquill setting with soft music and soft lights. Cloud B makes a great constellation night light that my 6 month old loves. It's part of my night time routine. As soon as he sees the stars, he knows it's bedtime a drifts right to sleep.
To this day my eldest tries to climb in our bed and begs to sleep with us. We occasionally allow him to becuase once you're out numbered by the kids, it's harder to find one on one quality time with each child.
You might loose some sleep or battle upfront but with anything in life, you get what you put into it. A lesson I've learned early on with parenting.
Good luck.
