Bad sleeper

Li

My baby is a bad sleeper at night 😩 only sleeps for 1-3 hours at a time. Breastfed with the occasional formula bottle we just started due to suspected dairy allergy/intolerance but she doesn’t love the formula. Anyone else dealing with little sleep? It seems like her nose snoring or gas pains wake her up a lot of the time. Last night we tried to get her to bed earlier and then she was awake from 2-4 eating and then took a big poop so I had to change her and then she would just not go back to sleep and if she fell asleep she’d wake right back up when I tried to transition her to the bassinet. 😑
