My MIL also worried about impact on birth children, but as soon little ones arrived she positively championed our children and adoption in every way ( she now has a job involving adoption!)
Very quickly some More points about birth children followed by adopted children:
Your adoption is very public, eg. One day at playgroup/ school you have two children, the next, three. ( I was asked several times if I’d started childminding!) Takes a bit of explaining to those people who are acquaintances, who you’d otherwise not really chat to, and then navigating their questions while maintaining three young children, takes skill!
Extreme uncertainty: yes, there’s uncertainty with BC growing up, multiply that many times with AC. We’ve wondered about FASD many times, ADHD; starting school there’s heightened thoughts about learning, socialising, add complications of attachment in there...basically, you’ll justifiably worry more and be poised to fight for support for your child/ children constantly. AC are far more emotionally exhausting from the outset. This applies in all adoption but with birth children in tow, yes possible impact on them, but wider impact on you as a family, so for example, it might limit what you all do. Small insignificant example but, camping with my impulsive, no limits three year old- no way! Shame, as the others would enjoy this. BC at this age were much more composed.
However! On the back of this, AC need a lot of channeling. Their impulsivity is scary, especially at the side of roads, but our BC are helping AC get into sport very early, channeling them. AD wants to do what her older siblings do- cycle, tennis, swim etc
BC have helped AC no end at school. They’ve navigated her in the playground, kept a watchful eye and reported back to me. Having them at school has helped in terms of attachment; she’s been able to sit with them in assemblies etc.hellped her feel secure.
It helps that we’re experienced parents, but we don’t know it all. AC need some different parenting techniques ( couldn’t use a sling with AC, they wouldn’t tolerate it...comfort was initially on their terms. Took 18months for AD to properly hug us etc, she trusted her siblings first, then us). We’ve learnt to be more playful, accepting and empathetic parents because of our AC-this has enriched the whole family.
Adoption process rightfully puts the needs of the adopted child as absolute paramount: can be frustrating as BC get sidelined, but slowly, once the children are placed, family life for all evolves from there.
Adoption process is all about ‘worst case scenario thinking’. It’s really really important to consider all this, think about the what ifs. Our reality has been hugely positive ( so far!). Three youngest have been playing happily in imaginary spaceships as I type this. AD has exceeded expectations across all areas at school this year and is very happy. Our youngest, who had speech delay, has now caught up, very socialable and also happy ( currently!)
I’m not sure how typical we are, I feel lucky, very fortunate to have these amazing kids.
In general all four get in very well together ( for now)....and are now begging to go to the park. Ha!
