Totally normal to feel this way Neaka! I felt guilty all the way through my second pregnancy, guilty that DS1 wasn't a bit older and that precious time would be devoted to someone else and not him, guilty that I didn't want to play on the floor with him because it was hard to get up, guilty if I didn't carry him because my back was so sore...
It's taken me a while to be able to devote quality one on one time to my older son. I have neither in childcare and only now, with DS2 being 7months is he sleeping long enough during the day for me to really spend some good time with DS1. But that 7 months isn't lost. It's been spent with DS1 getting to know DS2, and vice versa. It's been spent with them playing together, and DS1 learning that the entire world doesn't revolve around him (ok so maybe he doesn't totally get that yet
). Children are so adaptable, and yes it is undoubtedly hard to spend that same amount of quality time with the older child once the baby is here but if your pregnancy is anything like mine, you will be able to have better quality time once that baby is born because you won't be so uncomfortable, irritable or in pain (unfortunately you will probably be just as tired though
You may feel like your DS is pulling away from you but I can guarantee you that will change. When DS1 realised how much time I had to spend with DS2 he was quick to make me realise he wanted my attention a bit more.
Things might feel like they aren't all going to fit in right now but it just does. You will more than make up for it when the baby is born because you spend a lot of time talking to your older child about the baby and teaching them how to interact. It's a beautiful experience and a new baby is also a bonding time for you and your older child. You will see
Try not to stress, like PP said you're giving your child a great gift
