I let my baby sleep during the day, whenever she needed. Trying to keep a baby awake is hard work, if they aren't happy cus they're tired then you're both not enjoying time together as much as you could if you let them nap as they needed. My baby woke during the night when she was hungry every night until 1 year old, but went straight back to sleep after a feed as we never stimulated her.
From 1 year old onwards, she sleeps all night every night in her own room ( unless unwell).
The best thing I ever did when she was around 6 or 8 months old was teach her to self settle and fall asleep on her own in the cot.
