My warning is that, breastfed babies may become bad sleepers till the time they are weaned, hence please be careful, or be prepared to stay up with them.
What happens with breastfed babies is that they learn to fall asleep while feeding which is a blessing till it becomes a habbit. As babies grow up, they start getting dependent on this method of falling asleep and then, every time their sleep breaks, they look to be fed again to fall asleep.
At around 7 months, my baby got into this habbit, and I was unable to do anything till I weaned her at 1 year of age. She would wake up several times at night and howl till she was fed. She hardly fed for a couple of minutes before falling asleep but my sleep was messed up through that period.
In order to avoid this, one must ensure that babies do not become dependent on breastfeeding to fall asleep. It is a very fine line and one has to be careful. Firstly, as soon as you start giving your baby 3 solid meals a day, one must cut all mid night feeds. Just give your baby water when she wakes. She may be hysterical for a day or two but will eventually understand that no feeds will be given to her at night. At this age baby’s who are growing normally, typically do not need a night feed but wake up just because they are used to it. This is easier to do in younger babies, just as you start solids, rather than when they 7-8 months old.
The other thing that one could do, is to ‘time feed’, whereby you feed your baby only for a particular amount of time say 10 or 15 minutes on each side depending on how much time she normally takes on each side and ensure that she does not fall asleep while feeding.
There can also be a milder approach to this whereby if they do get the habbit, its no big deal as with time their sucking reflex reduces and the habbit breaks with no much effort. So let them feel comfortable in their cozy nest and all you have to do is sacrifice some sleep.
