I plan to buy a co-sleeper cot as I'll be breastfeeding and last baby ended up in my bed every night anyway.
This might seem like a silly question but when baby goes to bed for the night ahead of me (hopefully!), there'll only be 3 sides to the cot, the other side obviously is my bed.. When the baby is very little or when I'm there that won't matter but as it gets a bit older if I'm not there surely it's possible for them to shuffle over and even out of the bed?
