Due to space limitations, our plan was to get a cot for our second rather than a cotbed. We've found one that turns into a cotbed but is cot sized so seems perfect. But... we're worrying that it won't give her enough space long-term. We're hoping to move house in about 2 years, so she'll be in it until at least 2-2.5. Our first throws herself around her cotbed. Will she be too cramped in the smaller bed, or won't it matter given she won't have known any different?
