My DS is 4 months old and This is my first baby. I love him to bits and I'm trying my best but I'm just feeling so overwhelmed at times. He needs constant attention and I'm just feeling so backed into a corner where
I don't have a minute to myself.
We've been fortunate in that dh has been able to work from home since he was born but the job has changed and he needs to be office based so I will be alone with DS this week. I sound so terrible for feeling down about that 
He wakes up at about 5am and that's it. He's napping about 20 minutes here and there but the rest of the time he just cannot be occupied by anything without dh or I doing it with him and him on our laps. Is this how it usually is? I feel embarrassed to ask friends, when they tell me their babies can be left on a playmat with a few toys and occupied for hours.
I think we've probably created this problem as we both have always picked him up and carried him at the slightest sound and now he can only be occupied while being carried.
Can I please ask what a 4 month old's day should be like, activities for them to do or how to get them used to being occupied without mum and dad just for a little while?
