If you have got used to feeding your baby at nights, remember it is fine till your baby is around 8 to 10 months of age. After that your baby must be eating at east 3 solid meals a day and sufficient mount of milk.
Firstly you need to be sure that your baby is getting sufficient amount of sleep during the day otherwise she will be too tired at night, may wake up occasionally and need help to sleep again.
Next it is important to make a regular routine. Keep time for play, for naps and for food and milk. Keep it regular and let the baby know what to expect next. A baby comforter may be a good idea to help your baby settle herself. When you let her know it is sleep time she should be able to quietly go to sleep…easier said than done. A consistent predictable routine will definitely be of great help to you and your little baby.
Help your baby feel safe and secure in her cot. Let the lighting be minimal, you may try soothing music, let the room be quite cool…overall the environment should be familiar, dark, cozy and comforting.
You may try sleep training if she still does not settle down, but do that as a last option. Make sure she is full and has eaten sufficiently. Try a bottle of milk close to bedtime, this will ensure she is full and has a sound sleep. Another good technique is to delay the feed consistently until it becomes the first morning feed.
This may be slightly tough but try comforting her, putting her to sleep in her cot itself, letting her know it’s not time for milk. The next time she wakes feed her and keep doing this regularly so that the night time feeding gets gradually eliminated.
You may try taking help from your partner as that may enable her to sleep though this may not work for all. You may try these techniques, but you need to understand that what works for some will not work for others. So keep trying till you succeed.
