Sleeping through the night

Kay • Hi I`m Kelly . My Hubby n I are super excited about our first baby !

I've been trying to get my 8months old baby girl to sleep through the night. Oh boy I keep failing! She's so unpredictable. She would wake up once through the night n other times 2-3-4 times. She goes to bed with a full tummy so I kn it's not hunger. Trying to keep her on a schedule but still fail🙃 any suggestions??
