5 month old sleep help 😩

My 5 month old does not sleep well at all day or night. I have a two year old too so you would think she could sleep through anything and everything. At night im getting up between 4-5 times. I give her a bottle and change her diaper (she HATES being wet) but I do it all in her crib. But she use to only get up once or twice. Im litterally getting no sleep and its killing me. Do I try to sleep train? Is it to early? Do I cut back on bottles? Help this momma out 😩😩😩😩
