The second will be hard for the first while. You get even less sleep than when you just had the one. Be prepared. The second you think you’ve finished up the chores and sit down one of them starts crying or demanding attention.
I’ve found our second really hard for the first 6 weeks, but she’s mellowing out now at 8 weeks old (just slept from 9-6, for example).
Melts my heart seeing our nearly 3 year old pat the baby’s head and cuddle her to comfort her when she’s crying. He’d ran into her room a couple of days ago while she was screaming and when I got in there 3 minutes later his head was resting on her tummy and he had his hand around her foot. She’d stopped crying. Almost draws a tear actually!
Plus, financially, a second kid is a very wise decision… You’re more likely to have someone willing to do a bit of looking after YOU when you’re old and decrepit.
All-inclusive, you will both be pushed farther into the stress/emotional turmoil zone for a while. This may feel like a disaster in the midst of it all, but as soon as things start to ease slightly you’ll be aware of the weight lifting.
