Brock went through a growth spurt at that age & is going through another one now. He gets a little unsettled when he goes through one but nothing like that. I up his bottle by 50mls throughout the day while he's going through it & drop it back afterwards.

I also sleep him in a sleeping bag with a dummy & he almost always sleeps through. I've found that the cherry type dummys stay better in his mouth overnight than the orthodontic ones do.
