so my babies are 3mos now and we bottle feed 7oz of breastmilk at around 6:30pm. we also feed 6oz of formula when they wake up around 1:00am. and then breastfeed when they wake up around 4:30am.

how do you get them to sleep through the night? should i put them to bed later? feed them more? or will they just adjust as they get older?
