How old is your LO and do they wake for a bottle in the night?
My little boy is just turned 7 Months Old and was sleeping through the night for a while from 3 Months but then went back to waking for a bottle around 3/4am again. He sleeps 7pm - 7.30am and when he wakes for the night feed he literally drinks the whole 7oz and goes right back to sleep like a dream.
I'm 100% sure he's waking because he's hungry as he doesn't take a dummy and doesn't cry just for me to pick him up and he is happy to go right back to sleep after his bottle.
Is this still normal for a 7 month old?
