DS is 7months and has been BLW from about 6 months (mainly because he won't take purees from a spoon). He has made real progress and I'm sure he's now eating at least some of the food (although he bites and chews so much it's hard to tell how much is missing from the bits on the floor!), but is now waking up at night for another bottle. That means he's now having 6x7oz bottles a day and shows no sign of cutting back. Has anyone else had this? Is it normal? Is it a problem?
