Sounds like a sleep regression. That's usually around 4-5months. Max started his bang on 4months but Morgan was nearly 5months when he started his.

She is most likely going through a growth spurt hun :) Waking through the night isnt an indication of ready to wean :) Maya still wakes up during the night and is on 3 meals and 3/4 breast feeds and snacks :) So weaning wont make them sleep Xx

App says she's 4months old but she's 5 btw
