When did your baby start changing their sleeping habits ?

When did your baby start changing their sleeping routine?

So my Little ones sleep routine is like this:

•7-8am feed, then up for about 3 hours (time being 10/11am).

•Then feeds again and stays awake for an hour or two (11/12)

•Then back to sleep for about another 3/4 hours. (3/4pm)

•Feeds and stays up again for two hours (5/6pm)

•Goes back to sleep by 7pm

•wakes by 10pm for another feed.

•Depends on the day but she’ll either fall back asleep till 1/2am or will be up till 12am and wants a feed then back to sleep

•Then wakes by 2am for a feed, and sometimes will stay awake for 2 hours, or she’ll go back to sleep .

•5/6am feed, then back to sleep

•7-8 am feed , and start the rotation again.

Is this to still be normal for being two months old ? Or should her sleep habits be starting to change? Do you help your child change sleeping habits by trying to keep them up more during the day or do they do it on their own? I’m a first time mom anyone’s input would be great!
