I have an 8 week old daughter that isn't meeting her developmental milestones. She has a very hard time keeping her head up (havent given a lot of tummy time until recently) and rarely does it and isn't wanting to engage much. She does occasionally smile and will sometimes talk and stare back. She was hospitalised at 6 weeks due to being sick. Doctor wasn't sure what it was and she was flushed with antibiotics which made her worse and gave her thrush. Fast forward to day and she's better but still having issues getting her to eat enough. Has anyone ever expected this? Has your child gained more neck/head control later on?
