My lg is 10 weeks and for the past few days has been cluster feeding and is just generally fussy/grumpy. Trying to find out if she could be having another growth spurt, had a big one at 5-6 weeks. Her sleeping pattern has also changed. Going down at 9ish but getting up twice? She was going down at 10.30 and only up at about 3am. I know this will change a lot but just wanted to see if anyone else has had this around 10 weeks too?
