1) Do not tickle baby after they just finished eatting.
Else you get a lot of spit up mess.
2) Cuddle baby when ever you can get away with it.
Sometimes how dirty the house is doesn't matter when you have a sleeping baby on your chest.
3) When a little boy flirts with you this much at almost 5 months
Don't wait untill 15 years to have the "birds and bees" talk.
