Chris that is wonderful news-congrats
Prepare for your heart to swell 10 times with an unselfish love u never knew u had.
I was a stay at home Mum for a few years there. My son is now in school and nearly 5.
If u don't mind advice I would:
Enjoy just lying in bed watching your baby. I was too driven to sort everything.
Have fun - I never realised babies are great fun, especially if u bring them swimming.
Take lots of photos and videos. Print them off.
Nap when your little lad naps - it will help keep you mentally and physically well.
Get out every day- be it a walk to a park, visit to friends or a playgroup or art gallery (little babies seem to love galleries) you will feel great for getting out of the house.
Don't go shopping without muslin squares / dribbles and most emergencies can use a muslin sq.
Finally be really selfish about getting enough rest. U may feel guilty but if u are unwell everything falls apart.
Congrats again and lovely to see u back again.
