Hi A.,
Our middle son was 2 when our youngest was born and he was a family bed boy too. What worked for us, for a while at least, may not work for you, but here it is ...
We put his toddler bed at the foot of our bed. That way, he wasn't alone, yet wasn't taking up precious room on our bed. It's really hard to say what will work, since this only worked temporarily with our son. He's back in our bed just about every other night or so. The other times, he shares a room with his big brother. Needless to say, he never liked sleeping by himself. Our youngest is now 12 months and you can just imagine how cramped a King sized bed can get with 4 people in it!
An important note**** I absolutely LOVE my babies and know that they grow up sooooo very fast. I try not to dwell on wanting my own space, only on giving my children the love and warmth they desire. They were in my womb for 8 months (all early!) and I get them for a very short time on the outside. I try to treasure the fact that they still want me. My oldest, now 6, is extremely independent and I don't get my cuddles with him now.
Hope this helps you.
Warmly,
R.
mommy to Cameron, Tristan and Logan
