I am going to try offering a more substantial snack (jar of fruit/veggie) and increasing the dinner portions. I hope it helps because I misssssss sleep!
Z's been doing that too, actually started at 9 months. She eats really well during the day and my once sleeping through the night baby is getting up in tears. Once I feed her she is fine and I'm luckily able to put her back to sleep. Not only do I think it is a growth spurt I also think it's the teething.
I don't think it is a growth spurt just more of a LOOK AT ME AND WHAT I CAN DO! I know at that time most babies are working on crawling, standing, pulling up and some even, ((((gulp)))) walking. It all can lead to burning more calories and more wakings.
9 months is a HUGE developmental leap and there is definitely a sleep regression. He's probably also working on some more teeth, improving his crawling, thinking about pulling up and walking, and there's some developmental stuff that I can't remember now. I know it sucks, but it's him, not you.
Re: Is there a 9mo growth spurt? or sleep regression?
Exactly!
