why do you want your babies to have fat rolls? Some babies are thin, there is nothing wrong with that at all.
Your watery EBM was probably more a factor of how many letdowns you got rather than the composition of your milk (more letdowns = more hindmilk), or how old your baby was when you expressed the milk. In the first few months, it will be much creamier then it adjusts and becomes more watery as baby gets older.
Your body will make the perfect milk for your baby, no need to do anything special.
