I'm also having my 1st child, EDD in May. We bought a baby cot (4-in-1) cos
1) the child can use it from newborn until 3-4yrs old (depending on his/ her weight)
2) the height is adjustable
We were hesitating to buy a playpen to put at my in-law house but my hubby noticed the height is lower and we have to bend down to carry the child; so in the end, we got another baby cot (exactly the same one) instead. Also worried the baby not used to the bed when we bring him home on weekends if both are different as my in-laws will be helping us to look after the baby during weekdays..
