I used to sleep with my baby in the cot till she fell asleep and i will creep out after. She will sleep throughout the night on her own. I tried carrying her till she sleeps (deep sleep btw) but SOMEHOW, God knows why, will stiiiiil wake up and cry when i put her in the cot. Sigh. Haha. Cn be pretttty frustrating at times but hey, we mommies cn ONLY, and, finally get our sleep when our kid sleeps. So I guess might as well accompany her inside so she'll feel secure and sleep soundly.
Feed her milk, Pat her softly till she sleeps. Or Prolly you can wait till she’s in a deep sleep then put baby down.
