Hello everyone! My son turned three yesterday, and we had a party for that occasion. We were preparing for two months ? And suddenly I realized that we weren't even prepared for the arrival of a daughter, and I feel like a hippopotamus already. The most pressing question is what to do with the crib? My son didn't sleep in it, he slept until 1.5 years old with us (there was a railing on the bed), then just moved to his own room and that's it. Should we invest in a crib or not? I can't decide?
