12 weeks and still not sleeping!

My LO is 12 weeks now and I’m absolutely exhausted!

She gets 3 short naps in the day but fights sleeping.

I started a little bedtime routine at 7 weeks and 9 out 10 times after naked time, Bath, bottle and bed she settles to sleep quite quickly. But will only drink an ounce or 2, daytime bottles it’s 6 ounces.

So bed between 6.30-7.30 and She then wakes at 10-11 then 1am and then its every hour maybe 2 if I’m lucky after that.

I try wait 3 hours to give her another bottle at night and try settle back to sleep but she’s not eating much at all at night time feeds and not sleeping for more than 2 hours is taking its toll on me! My husband works very long hours and physically demanding job so I really don’t want to be waking him for night time feeds.

Anyone else having the same? Any suggestions!!
