I drink out of a baby bottle most nights/mornings, not because i want to be a baby, but simply for ease. it is easier to hold a baby bottle in my teeth as i pull myself upstairs to bed, i spill less liquid when i drop the bottle in bed, if i drop the bottle when i am half way upstairs it doesn't break as it bounces down to the bottom, having a wide neck it is easier to tip the movicol powder and milk in than a water bottle. whenever i am not using a baby bottle i need to use a lidded cup with a straw or a pop top bottle as my hands do not coordinate well and i end up tipping a whole cup of drink down my front or choking on the liquid as i tip too much in at once! i do not care what others think, it works for me! i actually have a lidded cup at work with my name on so everyone knows it is only for me to use, and whenever i go in for a meeting it is always by the tea and coffee filled with juice waiting for me!(i don't drink tea or coffee)
